Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

PSA: Enable Tor as a simple way to make your node reachable.

Become one of the 10% of node operators that receive incoming connections.
Installing bitcoin core is easy, and with pruning it really isn't the space sink it is characterized as. Even a modest computer can complete the initial block download (IBD) and become a full node. But what some users (90%) find a bit more challenging, is how to become a listening node. Listening nodes are an important part of the network, and are simple enough to enable. I can think of 4 ways to do it:
  1. Operate on an OS and Network that support uPnP, allowing bitcoin to open the ports for you.
  2. Subscribe to a VPN that allows you to open ports through their service.
  3. Manually configure your OS and network to forward port 8333 and 18333.
  4. Run Tor and direct bitcoin to listen through it.
I'll discuss #4. Obviously #1 or #2 are easier, but require a VPN subscription or uPnP enabled HW. And if you live in a dorm or don't control the network, Tor may be the only free option available.
As a bit of background, bitcoin supports three networks that your node can listen on:
Obviously, the more you enable, the better, but here are the basic steps for Tor in broad strokes. If you have any questions post them here and I'll see if we can't help you out:
  1. Download, verify1 and install Gpg4win
  2. Download, verify2, install, and launch Tor Browser
  3. Download, verify3, install, and launch Bitcoin Core
  4. Launch and Admin command console in the directory containing tor.exe
  5. Install the Tor service: tor.exe --service install
  6. CD to service dir: cd %windir%\ServiceProfiles\LocalService\AppData\Roaming\tor
  7. Create and edit a file called torrc with the contents suggested below
  8. Restart tor: tor.exe --service stop && tor.exe --service start
  9. Record the hostname: type .\HiddenService\hostname as
  10. Add the bitcoin.conf options suggested below
  11. Restart the bitcoin-qt program
  12. (Optional) Activate the bitnodes crawler at https://bitnodes.io/nodes/-8333/
It may take a while for your node to show up on bitnodes. I've found the check button sometimes has trouble with onions. Of course you don't need to do it, but it can provide a simple way to check status once your on the list.

torrc file: (replace c:\windows with the proper path as needed)

```

Change to C:\Windows\ServiceProfiles\LocalService\AppData\Roaming

Log notice file \tor\service.log

Bridges may be needed if the Gov't shuts down Tor exit nodes. Get Bridges by

emailing [email protected] from Gmail (only) and uncomment as follows:

Bridge obfs4 : cert= iat-mode=

HiddenServiceDir \tor\HiddenService HiddenServiceVersion 2 HiddenServicePort 8333 127.0.0.1:8333 HiddenServicePort 18333 127.0.0.1:18333 ```

bitcoin.conf file: (entries to be ADDED)

```

Change to what you recorded earlier

onion=127.0.0.1:9050 listen=1 externalip= discover=1 ```

Cannot create wallet with Trezor

Hi guys, I am stuck trying to create a wallet for my Trezor with Electrum 4.0.4 on Linux:
I get to the point of entering the password twice and then selecting the path. But after that it just says
'Please wait' and then the window hangs. The only way to do something is either kill the process or send a `SIGINT` signal.
Interestingly after sending a SIGINT the window unfreezes and asks me again for the password (also during the whole freeze the Trezor device writes that I should enter my password). After entering the password again I get an empty error window and on closing it everything closes.
I started electrum with `electrum -v` to get some logs:

Full node sync speed

I'm syncing a full node on a Raspberry pi 4 with 8GB memory, external disk drive (not ssd), broadband internet. It's going extremely slow--estimated time about 4 years.
Google has turned up all kinds of advice like setting:
dbcache=4096 (setting aside half my ram)
blocksonly=1
banscore=10
listen=0
par=-1
When I run top, I see bitcoin-qt is only using about 12% of the CPU. When it boots and is loading the block index, I see that go up to 100+%. So for whatever reason, it's not fully utilizing the CPU on the machine while processing blocks.
I tested my internet connection and have 56Mbps down, 6Mbps up.
My only theory is that the external hard drive is being the bottleneck. Is there anything else to do, or should I order a SSD?

The White Dragon : A Canadian Dragon Portfolio

Alright guys, Ive been working on this for a while and a post on here by a guy describing his portfolio here was the final kick in the ass for me to put this together. I started writing this to summarize what Im doing for my friends who are beginners, and also for me to make some sense of it for myself
Hopefully parts of it are useful to you, and also ideally you guys can point out errors or have a suggestion or two. I'm posting this here as opposed to investing or canadianinvestor (blech) because they're just gonna tell me to buy an index fund.
This first section is a preamble describing the Canadian tax situation and why Im doing things the way that I am. Feel free to skip it if you dont care about that. Also, there might be mistake regarding what the laws are here so dont take my word for it and verify it for yourself please.
So here in Canada we have two types of registered accounts (theres actually more but whatver). There is the TFSA "Tax Free Savings Account", and RRSP "Registered Retirement Savings Account"
For the sake of simplicity, from the time you turn 18 you are allowed to deposit 5k (it changes year to year based on inflation etc)in each of them. That "room" accumulates retroactively, so if you haventdone anything and are starting today and you are 30 you have around 60k you can put in each of them. The prevailing wisdom is that you should max out the TFSA first and you'll see why in a minute.

TFSA is post tax deposits, with no capital gains or other taxes applied to selling your securities, dividends or anything else. You can withdraw your gains at any time, and the amount that you withdraw is added to the "room" you have for the next year. So lets say I maxed out my TFSA contributions and I take out 20k today, on January of next year I can put back in 20k plus the 5 or whatever they allow for that year. You can see how powerful this is. Theres a few limitations on what is eligable to be held in the TFSA such as bitcoin/bitcoin ETFs, overseas stocks that arent listed on NYSE, TSX, london and a few others. You can Buy to Open and Sell to Close call and put options as well as write Covered Calls.

The RRSP is pre-tax deposits and is a tax deferred scheme. You deposit to lower your income tax burden (and hopefully drop below a bracket) but once you retire you will be taxed on anything you pull out. Withdrawing early has huge penalties and isnt recommended. You are however allowed to borrow against it for a down payment as a first time home buyer. The strategy with these is that a youngperson entering the workforce is likely to be in a fairly low tax bracket and (hopefully) earns more money as they get older and more skilled so the RRSP has more value the greater your pre-taxincome is. You can also do this Self Directed. Its not relevant to this strategy but I included it for the sake of context.
Non registered accounts ( or any other situation, such as selling commercial real estate etc) is subject to a capital gains tax. In so far as I understand it, you add all your gains and losses up at the end of the year. If its a positive number, you cut that number IN HALF and add it to your regular pre-tax income. So if I made 60k from the dayjob and 20k on my margin account that adds up to 70k that I get taxed on. if its a loss, you carry that forward into the next year. Theres no distinction between long term and short term. Also physical PMs are treated differently and I'll fill that part in later once I have the details down.
The reason why all that babble is important is that my broker Questrade, which isnt as good as IB (the only real other option up here as far as Im aware) has one amazing feature that no other broker has: "Margin Power"
If you have a TFSA and a Margin account with them, you can link them together and have your securities in the TFSA collateralise your Margin account. Essentially, when it comes to the Maintenance Excess of the Margin Account QT doesnt care if its in the TFSA *or* the Margin!
You can see how powerful this is.
------------------------------------------------------------------------------------------------------------------------------------------------
So as you can tell by the title, a lot of this is heavily inspired by Chris Cole's paper "The Allegory of the Hawk and the Serpent". You can read it here: https://www.artemiscm.com/welcome#research
Between it, his interviews and my mediocre options skills at the time my mind was blown. Unfortunately I didnt know how to do the Long Volatility part until after the crash in March but I've since then had nothing but time to scour the internet and learn as much as I could.
The way I interpret this isnt necessarily "what you should have right now", but what abstracted model they were able to backtest that gave them the best performance over the 90 years. Also, a lot of my portfolio I already had before I started trying to build this.
As such my allocations dont match the proportions he gave. Not saying my allocations are better, just showing where they are at this time.
I'm going to describe how I do Long Volatility at the end rather than the beginning since the way *I* do it wont make sense until you see the rest of the portflio.

Physical PMs 22%
I'm not sure wether he intended this to be straight up physical gold or include miners and royalty streaming companies so I will just keep this as physical.
I consider Silver to be a non-expiring call option on gold, so that can live here too. I am actually *very* overweight silver and my strategy is to convert a large portion of it to gold (mostly my bars) to gold as the ratio tightens up.
If youre into crypto, you can arguably say that has a place in this section.
If an ETF makes sense for part of your portfolio, I suggest the Sprott ones such as PHYS. Sprott is an honest business and they actually have the metal they say they have. If you have enough, you can redeem your shares from the Royal Canadian Mint. The only downside is that they dont have an options chain, so you cant sell covered calls etc. Simple enough I suppose.
One thing to bear in mind, there is a double edged sword with this class of assets. They're out of the system, theyre nobody's business but your own and theres no counter party. That unfortunately means that you cant lever against it for margin or sell covered calls etc. You can still buy puts though (more on that later)

Commodity Trend (CTA) 10%
https://youtu.be/tac8sWPZW0w
Patrick Ceresna gave a good presentation on what this strategy is. Until I watched this video I just thought it meant "buy commodities". A real CTA does this with futures also so aside from the way he showed, there are two other ETFs that are worth looking at.
COM - This is an explicit trend following ETF that follows a LONG/FLAT strategy instead of LONG/SHORT on a pile of commodity futures. So if they get a "sell" signal for oil or soybeans they sell what they have and go to cash.
COMT- Holds an assortment of different month futures in different commodities, as well as a *lot* of various related shares in producers. Its almost a one stop shop commodities portfolio. Pays a respectable dividend in December
If you want to break the "rules" of CTA, and include equities theres a few others that are also worth looking at
KOL- This is a coal ETF. The problems with it are that a lot of the holdings dont have much to do with coal. One of them is a tractor company. A lot of the companies are Chinese so theres a bit of a red flag.
Obviously Thermal Coal, the kind used for heating and powerplants isnt in vogue and wont be moving forward...but coking coal is used for steel manufacturing and that ain't going anywhere. The dividend is huge, pays out in December. A very very small position might be worth the risk.
Uranium- I'm in URA because thats the only way for me to get exposure to Kazatoprom (#1 producer), which is 20% of the holdings. The other 20% is Cameco (#2 producer)and then its random stuff.
Other than that I have shares in Denison which seems like its a good business with some interesting projects underway. I'm still studying the uranium space so I dont really have much to say about it of any value.
RSX- Russia large caps. If you dont want to pick between the myriad of undervalued, high dividend paying commodity companies that Russia has then just grab this. It only pays in December but it has a liquid options chain so you can do Covered Calls in the meantime if you want.
NTR- Nutrien, canadian company that was formed when two others merged. They are now the worlds largest potash producer. Pretty good dividend. They have some financial difficulties and the stocks been in a downtrend forever. I feel its a good candidate to watch or sell some puts on.
I'm trying to come up with a way to play agriculture since this new phase we're going to be entering is likely to cause huge food shortages.

EURN and NAT- I got in fairly early on the Tanker hype before it was even hype as a way to short oil but I got greedy and lost a lot of my gains. I pared down my position and I'm staying for the dividend.
If you get an oil sell signal, this might be a way to play that still.

Fixed Income/Bonds 10%

Now, I am not a bond expert but unless youre doing some wacky spreads with futures or whatever... I dont see much reason to buy government debt any more. If you are, youre basically betting that they take rates negative. Raoul Pal of Real Vision is pretty firm in his conviction that this will happen. I know better than to argue with him but I dont see risk/reward as being of much value.
HOWEVER, I found two interesting ETFs that seem to bring something to this portfolio
IVOL- This is run by Nancy Davis, and is comprised of TIPS bonds which are nominally inflation protected (doubt its real inflation but whatever) overlayed with some OTC options that are designed to pay off big if the Fed loses control of the long end of the yield curve, which is what might happen during a real inflation situation. Pays out a decent yield monthly
TAIL- This is a simpler portfolio of 10yr treasuries with ladder of puts on the SPX. Pays quarterly.

Equities 58% (shared with options/volatility below)
This is where it gets interesting, obviously most of this is in mining shares but before I get to those I found some interesting stuff that I'm intending to build up as I pare down my miners when the time comes to start doing that.
VIRT- I cant remember where I saw this, but people were talking about this as a volatility play. Its not perfect, but look at the chart compared to SPY. Its a HFT/market making operation, the wackier things get the more pennies they can scalp. A 4% dividend isnt shabby either.
FUND- This is an interesting closed end fund run by Whitney George, one of the principals at Sprott. He took it with him when he joined the company. Ive read his reports and interviews and I really like his approach to value and investing. He's kind of like if Warren Buffett was a gold bug. Theres 120 holdings in there, mostly small caps and very diverse...chicken factories, ball bearings all kinds of boring ass shit that nobody knows exists. Whats crucial is that most of it "needs to exist". Between him, his family and other people at Sprott they control 40% or so of the shares, so they definitely have skin in the game. Generous dividend.
ZIG- This is a "deep value" strategy fund, run by Tobias Carlisle. He has a fairly simple valuation formula called the Acquirer's Multiple that when he backtested it, is supposed to perform very well. He did an interview with Chris Cole on real Vision where he discusses how Value and Deep Value havent done well recently, but over the last 100 years have proven to be very viable strategies. If we feel that theres a new cycle brewing, then this strategy may work again moving forward.

I want to pause and point out something here, Chris Cole, Nassim Taleb and the guys at Mutiny Fund spend a lot of effort explaining that building a portfolio is a lot like putting together a good basketall team. They need to work together, and pick up each others slack
A lot of the ETFs I'm listing here are in many ways portfolios in and of themselves and are *actively managed*. I specifically chose them because they follow a methodology that I respect but I can't do myself because I dont have the skill, temperament or access to.
The next one is a hidden gem and ties into this. I'm not sure how much more upside there is in this one but man was I surprised.
SII- Sprott Inc. I *never* see people listing this stock in their PMs portfolios. A newsletter I'm subscribed to described this stock as the safest way to play junior miners. Their industry presence, intellectual capital and connections means that they get *the best* private placement deals in the best opportunities. I cant compete with a staff like theirs and I'm not going to try. I bought this at 2.50, and I liked the dividend. Since then they did a reverse split to get on the NYSE and like the day after the stock soared.
When it comes to mining ETFS I like GOAU and SILJ the best. None of their major holdings are dead weight companies that are only there because of market cap. I dont want Barrick in my portfolio etc.
SGDJ is a neat version of GDXJ.
Aside from that my individual miners/royalty companies are (no particular order)
MMX
SAND
PAAS
PGM
AUM
AG
MUX
RIO- Rio2 on the tsx, not rio tinto
KTN
KL
Options/Volatility: varies
So this is where we get to the part about options, Volatility and how I do it. I started out in the options space with The Wheel strategy and the Tastytrade approach of selling premium. The spreads and puts I sell, are on shares listed above, in fact some of those I dont hold anymore.
Theres tons of stuff on this in thetagang and options so I wont go into a whole bunch (and you shouldnt be learning the mechanics from me anyway) but theres one thing I want to go over before it gets wild.
If I sell a Cash Secured Put, from a risk management perspective its identical to just buying 100 shares of the underlying security. You are equally "Short Vol" as well, it just that with options
its a little more explicit with the Greeks and everything. But if I use my margin that I was talking about earlier, then I can still collect the premium and the interest doesnt kick in unless Im actually assigned the shares.
But if I sell too many puts on KL or AG, and something happens where the miners get cut down (and lets be real, they all move together) my margin goes down and then I get assigned and kaboom...my account gets blown up
So what I need to do, is balance out the huge Short Vol situation in my portfolio, be net Long Vol and directly hedge my positions. Since the overwhelming majority of my equities are all tied to bullion this is actually a very easy thing to do.

Backspreads
https://youtu.be/pvX5_rkm5x0
https://youtu.be/-jTvWOGVsK8
https://youtu.be/muYjjm934iY

So I set this up so the vast majority of my margin is tied up in these 1-2 or even 1-3 ratio put spreads that *I actually put on for a small credit*, and roll them every once in a while. I run them on SLV, and GDX.
I keep enough room on my margin so I can withstand a 10% drawdown before it sets off the long end of the spreads and then I can ride it out until it turns around and we keep the PM bull market going.
Theres another cool spread I've been using, which is a modified Jade Lizard; if already hold shares, I'll sell a put, sell a covered call, and use some of the premium to buy a longer dated call. Ive been running this on AG mostly.
I have a few more spreads I can show you but Im tired now so it'll have to wait for later.
As I said multiple times, I do intend to trim these miners later but now isnt the time for that IMO. I'm also monitoring this almost full time since I have an injury and have nothing better to do until I heal :p

IOTA funds were stolen (3.49Ti ~500k$) on 12th March 2020 after network relaunch [longread]

Hey CC comunity!
First of all, sorry for posting it a bit late I have some serious changes in my lifestyle and business due to Coronavirus situation in the world. For those who are infected I wish to get well soon and all the rest to stay safe and to stay home.
Here is my short story:On March 12th I made similar but short post regarding my stolen IOTA in the sub IOTA. First of all I met around 50% downvotes, I don’t know why but it seems that IOTA’s community don’t want to see posts regarding stolen IOTA, I got a lot of critics for using Trinity wallet instead of hardware and so on. But I see nothing strange using desktop wallet and it doesn’t matter whether it is IOTA Trinity or Bitcoin QT or Ethereum wallet unless in has strong manually typed password, VPN connection and some other security things. Or maybe IOTA’s community was afraid of unwanted bad attention during that market crash that day. So because of that experience I decided to make a post here at CC.
Some short reminder of what happened before my funds got stolen (https://status.iota.org)
Some news:https://www.coindesk.com/iota-foundation-suspends-network-probes-fund-theft-in-trinity-wallethttps://cointelegraph.com/news/iota-foundation-investigates-funds-allegedly-stolen-from-trinity-walletshttps://www.theblockcrypto.com/post/55955/iota-foundation-funds-stolen-users-of-trinity-wallet
If you don’t want to read that news here are some facts with timestamp:
February 12th 2020 - 18:55
As a precaution we ask you to keep your Trinity wallet closed for now.
February 12th 2020 - 19:20
After initial investigation we decided to turn off the Coordinator to make sure no further theft can occur until we find out the root cause of these thefts. (Lets say: “blockchain stopped”)
February 14th 2020 - 17:50
We have found the exploit.
February 15th 2020 - 00:50
After successfully identifying the attack on Trinity through a third-party integration
February 17th 2020 - 02:23
We have just released a safe version of Trinity Desktop to allow users to check their balance and transactions. This version (1.4.1) removes the vulnerability announced on 12th February 2020. (I’ve installed this particular version)
February 21st 2020 - 18:43
ACTION MAY BE REQUIRED TO PROTECT YOUR TOKENS IN TRINITY.
February 24th I left my country for some working trip
February 26th 2020 - 13:10
We are currently in the testing phase of the migration tools, once testing completes the tools will be audited by a external party. If this all goes well we are aiming to release these tools later this week.
February 29th 2020 - 19:15
The Seed Migration Tool is now available.
March 6th 2020 - 15:17
REMINDER: You have until 5PM (UTC), Saturday, 7th March to migrate your seed.
I’m still out of the country but I’m pretty sure I’m safe coz I’ve installed 1.4.1 wallet which removes the vulnerability.
March 8th 2020 - 18:15
The migration period has ended.
I got back to my country
March 10th 2020 - 16:45
We are aiming to resume value transactions around 5PM CET today.
March 10th 2020 - 18:15
The network coordinator has resumed operation. (Let’s say “blockchain restarted”)
Now my turn:

Same day I’ve made first post on reddit to get some attention to the happened situation. At the same time I’ve start to search for some technical support through over official telegram groups:
iotatangle
(https://imgur.com/McmrF3L)I’ve send a message where I’ve stated that my funds were stolen after network relaunch. Got some response from user Basti he invited me to another group with general discussion.screen shot 1 (https://imgur.com/hvDuoQA)screen shot 2 (https://imgur.com/MewdNm5)
Our short dialogue continued at the general discussion group iotacafe
(https://imgur.com/e9ErcPW) Where Basti introduced me to the IOTA Foundation member Antonio Nardella (https://imgur.com/WxZRk8N)
Before I started my conversation with Antonio I decide to get some information about him. I’ve found a Medium post with some welcoming words to Antonio Nardella.
(https://imgur.com/KK4zoOv) telegram(https://imgur.com/VquNCpi) medium
Seems legit.
Of course I couldn't be 100% sure it was him but the information he asked for wasn’t really sensitive so decided to share all I knew and all I did.
(https://imgur.com/X3Ha02Q) He also mentioned a wallet integrated service MoonPay, whether I used the wallet with this service or not and it didn’t matter if I used the service it self.
I’ve informed him that I used 1.4.1 wallet which was recommended to install on February 17th 2020(https://imgur.com/iZdNcm7)
When he gathered all the necessary information regarding loss of funds he took the time for sending this information for investigation team.
After a long awaited answer I got the same day this:
“Hello, I was informed that the loss of tokens is associated to the person/team responsible for the Trinity wallet attack via a third-party dependency from Moonpay.
As suggested on https://status.iota.org/, please file a report with the local police and to cite the following case number when doing so: LKA Berlin, Center for Cybercrime, case number: 200213-1717-i00290.”(https://imgur.com/Gov1v0i)
So, reinstalling the wallet didn't help me to avoid the loss of funds.
Well if my funds are proved to be stolen then it means - yes, I’ve used the Trinity wallet between the December 17th 2019 and the February 17th 2020. And yes, I wasn’t able to make seed transition during the given period. I was out of the country starting form Feb 24th till March 8th. I can even proove it with my border passing stamps… You know I didn’t use to take 4.5Ti with me just in case I would need an urgent seed transition. Could you imagine thousands of people with their multimillion Bitcoin holdings carrying private keys everyday with them just in case they would need seed transition… The funds were stolen not by my mistake but IOTA developers/foundation/etc (lets say IOTA team) mistake.
At the end of my story I want to take your attention to the fact that I didn’t compromise my PC neither wallet nor password nor seed. All my fault was for using the desktop wallet… How can you imagine your user without using your software/services/etc… I want to publicly call IOTA team (especially mr David Sonstebo) to cover not only those which were to happen back in the Feb 2020 but all the loses which were caused by that wallet vulnerability.

Thanks for reading and thanks for your time!

There is no "best" hardware wallet.

My first hardware wallet was a spare computer that never connected to a network and I used it to sign transactions with bitcoind by printing the txid's on paper. That was the "best" hardware wallet.
Then my spare laptop that never connected to a network and ran bitcoin-qt to was the "best" hardware wallet. Then that laptop was upgraded to Electrum (edited: typed "Ethereum" in original post).
Then I moved to the first-generation Trezor. And now I have a Ledger Nano S. Eventually I will move to something else that hasn't even been released yet.
Bottom line: There is no "best" hardware wallet. There are only wallets that are the "best" for the person using them at that specific time.

We made adjustments to the Russian and English versions of the site, including support for Korean and Chinese for each section of the site. Professionals in their field, native speakers translated and adapted the information as it should be, and we, in turn, structured and framed it properly. So welcome!

QR Codes for Asian Audience


https://preview.redd.it/bv08bzm0we151.png?width=496&format=png&auto=webp&s=338ba001c3a5d6999347165e7bd725b5be7f4913
Our friends and residents of Asian countries actively use QR codes in their lives, both when paying in stores and when working with websites. QR codes are used almost everywhere when renting a car or bike, we just open the phone, scan and the mode of transport becomes available for use, anything is available for rent, even a battery, even an umbrella.
“It was a hot May day. Seven-year-old Wang Jiaozui came out of school and saw his grandfather, who came to pick him up. He was standing in the sun, and his shirt was soaked with sweat. Jiaozui invited the grandfather to buy a cold Cola in the shop, but he forgot her purse at home. It turned out that this is not important — the boy took his grandfather’s smartphone and called the payment app with a QR code on the screen.” ©
What to say if QR codes are used even to identify entire farms. By pasting QR codes on farm buildings and then scanning them, government inspectors can quickly figure out who owns the building and whether its owners are violating any laws.

We must be on the trend! Now a special library generates QR codes for the desired page, any tab on the site tkeycoin.com in Chinese and Korean-accompanied by a QR code that leads to the requested page: fast, convenient, and simple.
https://preview.redd.it/73rscop3we151.png?width=700&format=png&auto=webp&s=c83229e56d612450370b43b06910225701454c60
Providing this opportunity to our colleagues and future users of Tkeycoin from Asia is a friendly approach and most importantly, a strategic step on our part. After implementing QR codes, we are undoubtedly drawn into the convenience of this function, which we recommend to You:) If you like it, we will make QR codes on the Russian and English versions of the site.

Buying and withdrawing cryptocurrency to a Bankcard


https://preview.redd.it/9i8ykpv5we151.png?width=700&format=png&auto=webp&s=3a31d0a463de5e08f94a5b27a472fb8b53ab044e
On the site, you can now buy Bitcoin for pound, dollars, euro, and any other currency. This is a powerful automated service for instant exchange of fiat currencies for cryptocurrencies. The system works around the clock and seven days a week, allowing everyone to conduct exchanges at any time of the day and in the shortest possible time.
Withdrawal to a Bank card will be available until the end of the month, we finish the details, the page is available now, and the withdrawal itself will be activated during this week. You can buy Bitcoin, Ethereum, or any other currency right now.

https://preview.redd.it/o8z0c4b7we151.png?width=700&format=png&auto=webp&s=b4d684f09acd914316c986482b8dadf88718c618
These features are the future for the function of purchasing any product or service for TKEY at any point of sale, which will form the basis of the mobile app, quickly, conveniently, and most importantly, observing the letter of the law.
All we do is build an Empire that is being built before your eyes. Every service and product is connected, so any update promises the appearance of even more cool and effective features than before.

Buying cryptocurrency for pound, dollars, euros, and other currencies

At the end of February, we told you that we are working on building a payment service that will include the provision of services: buy cryptocurrencies, sell a cryptocurrency, withdraw cryptocurrency to Bank cards, etc.
This day has come, now you can buy Bitcoin (BTC), Ethereum (ETH), Tether USDT, Basic Attention Token (BAT), Algorand (ALGO), Tron (TRX), OKB (Token Okex.com).

https://preview.redd.it/1pm2cnv8we151.png?width=700&format=png&auto=webp&s=69473d2e5ed1b8dc75189362b46906752be29895
The purchase is available in any currency: Russian ruble, US Dollar, Euro, British pound, Ukrainian hryvnia, Indonesian rupiah, South Korean won, Japanese yen, Turkish Lira, Argentine peso.
As you can see, the currency corridors are quite extensive, which allows you to make exchanges fast and at a favorable rate. Just choose the right pair to exchange or buy, available fiat currencies: RUB, USD, EUR, GBP, UAH, IDR, KRW, JPY, TRY, ARS, available cryptocurrencies: BTC, ETH, BAT, USDT, ALGO, TRX, OKB.
Even if this wide list does not include the currency you want to buy, such as Bitcoin or USDT, it’s okay — the service will automatically convert your currency into the payment currency and the Bank will make the exchange. Exchanges take place within 1–3 minutes, it is enough to pass quick verification once, which allows you to work with a volume of > 15,000 euros per month.

https://preview.redd.it/0ln5uttawe151.png?width=700&format=png&auto=webp&s=35de9e413db35bb53f39332aa4197cd54a3e211c

Exchange of cryptocurrencies for pound, dollars, euros, and withdrawal of Bankcard

In addition to the fact that you can now easily buy a cryptocurrency for fiat currencies, pound, dollars or any other, during this week we will finish work on the withdrawal to a Bank card and you can easily withdraw your profit to the card, the most important thing is that this is a completely legal method, and all operations pass through banks and jurisdictions where work with digital assets is legalized.
This means that when you buy or make a withdrawal to the card, you get legal funds that are credited to you by the Bank or payment system.
If you are used to working with effective tools that work in a new way, or rather correctly and legally, then this service is for you. Fast crediting, easy exchange, a large selection of currency pairs, that’s what the company is betting on.
We work with the most reliable third-party partners to make your cryptocurrency process easy and convenient, and most importantly safe for You. The service supports plastic and virtual Bank cards VISA, MasterCard, MIR, and other payment systems for fast payment processing.

https://preview.redd.it/x1jnm1ccwe151.png?width=700&format=png&auto=webp&s=f86fc353ad5f207db8d233821204b521ba0b3d0e
On the exchange page, you can choose any currency pair to exchange in the opposite direction, for example, GBP to BTC or USD to BTC. Choose a suitable pair for exchange, available fiat currencies: RUB, USD, EUR, GBP, UAH, IDR, KRW, JPY, TRY, ARS, available cryptocurrencies for exchange: BTC, ETH, BAT, USDT, ALGO, TRX, OKB.
How it works
When buying cryptocurrency for the first time, your Bank reserves (holds) the requested amount, then this amount is transferred to the authorization waiting state. As soon as the Bank freezes the fiat funds, the service fixes the exchange rate at the time of creating the application, reserves the cryptocurrency, and provides you with 30–40 minutes to complete verification. After successful verification, the service charges cryptocurrency to the wallet.

Quick verification

Verification takes 2–3 minutes and requires only one time to perform operations every day. The “Know Your Customer” (KYC) procedure is necessary to exchange cryptocurrencies for fiat currencies.

https://preview.redd.it/3y0pmzrdwe151.png?width=597&format=png&auto=webp&s=01a92651b67f2df70f83082cfcd3d1fdee5491b4
As you understand, you need to pass verification 1 time, regardless of whether you withdraw funds or buy currency, after passing verification, all services are available to You without any further confirmation.

New currency

Support for other currencies, including TKEY, will be added gradually and highlighted through service updates. As for the TKEY exchange, it will become available in exchange services after listing on the exchange. Listing on an exchange allows you to automate the exchange process, link the necessary services, and most importantly, the exchange provides liquidity, which is key when we talk about exchanging for a particular currency.
We will tell you more about the operation of the service and its advantages, chips, in a separate material dedicated to the withdrawal and purchase of cryptocurrencies for fiat currencies, as well as touch on various banking issues and tell you how you can combine the SWAP service for more efficient exchange and withdrawal to the card.

Charitable activity

By making an exchange or purchase of cryptocurrency, you help children and people who need our help. We deduct 0.1% of the profit from each transaction to charity funds.
This is the fastest and most comfortable way of charity, which allows you to bring together people who are not indifferent to other people’s problems. TKEY enables people to do good deeds, and the resulting turnover profit of 0.1% is sent to charity funds every month. Together with You, we create new opportunities for people in need who need help — “Big things have small beginnings”.
How does it work?
You have made an exchange or purchase operation, the company has accumulated the volume of these operations for a month->the company has chosen a charity Fund->sent funds to the charity Fund’s account. Priority charity funds are children’s aid funds. You can always suggest a candidate for a particular Fund by sending a message to [[email protected]](mailto:[email protected]).
Why do we write Funds and not a Fund?
This is the first launch of the service, so depending on the monthly volume, we will focus on distributing funds to one charity or several. For example, if we have accumulated $ 10,000, we can distribute $ 5,000 to 2 funds. if we have accumulated $ 100, it is logical that we will only send this amount to 1 Fund. With the development of the service, we will be able to focus on several funds, which we will actively help due to the received volume.

New sections, improvements for existing services

Menu logic and site structure

The menu logic has been revised. now more items are available on the menu and they are divided into sections. Navigation through the sections has become much easier and more convenient. for some sections, QR codes are available for Russian and English-speaking audiences, and for representatives of Asian countries, all sections are available by QR code.

https://preview.redd.it/d9ntj1hfwe151.png?width=700&format=png&auto=webp&s=6c068daa450e5f824829a9457bc1bc183615f466

Right on the page there is a FAQ section, in which we disclose answers to questions, for example: How are You going to solve the scalability problem, or why did you choose Phoenix as the logo and symbol of the project, or how do you exchange cryptocurrency for pound or dollars? As you can see, you can get answers to different questions, depending on the topic of the site section.

https://preview.redd.it/8utkvv6iwe151.png?width=700&format=png&auto=webp&s=d493ec784d74c5982486e36fe3b4bcbcb6d57335

What is waiting for us in the nearest future?

In addition to various improvements, connecting services, our team has been working every day on other main areas of the Tkeycoin project, which are already being prepared for the next release and we will tell you what updates, what plans, events, and what else will be interesting this year.

Online conference with management

An online conference in question-answer format will be organized. The main task of the conference, in addition to questions and answers, is to discuss plans, talk about new directions, touch on issues of legislation, and analyze current issues of users.
The online meeting format will allow you to get feedback and discuss a large number of issues in a short time. Questions related to technical support and other questions that can be answered through the administration will not be discussed.
The meeting involves the development, constructive, and suggestions from users for further development of the Tkeycoin project. If you are interested in participating in the conference, you can also make business proposals during it, please use the time to your advantage. We work for you.

New content: reports, new categories, useful information

Based on user feedback, we introduce new categories to our content plan:
Reports This section will be accompanied by information about the work done by the team for the month, the format of submission — abstracts, highlights. This format will help establish feedback between users and developers.
Question-answer
In addition to the content that we produce ourselves, users have questions that arise during the process of working with the project’s services, as well as during interaction with the project itself. To avoid making guesses and making up stories, we have introduced the question-answer category.
Users ask questions in comments, and the company prepares answers based on the questions and they are published in the post. Depending on the number of questions, the post generates all the answers, or the post is divided into parts if the number of questions for the past period was the largest. In addition to asking questions, you can make suggestions to the project, for example, about new features or directions.
This format also builds feedback and helps to improve all services. the most important thing is that it can not only help us but also you, as the offer and questions will help you focus on the tasks that the end-user wants to see.

TKEY-POOL (Tkeycoin pool)

We are completing the work and debugging of the official pool for Tkeycoin, this is a completely new approach for mining Tkeycoin. The pool will feature higher performance and stable architecture, a light interface, and objective commissions.
A pool is a highly loaded system that works 24/7/365, it turns out that such a product hides a sufficient number of lines of code and, most importantly, is built on a reliable architecture that can withstand +50000–100000 miners, not to mention the number of connected devices for this number of miners.
A cryptocurrency pool is a combination of the hardware power of many miners at once to increase the probability of finding a block. The reward for a block obtained by the pool is distributed among all participants.
The TKEY pool is developed taking into account the features of the Tkeycoin blockchain, including multi-blockchain, transaction model, hashing, blocks, and other nuances that are an upgrade of the blockchain among others. Together with the pool, the TKEY network is being tested: high loads, attacks, and other tests that show positive results, proving that the TKEY blockchain can work under any loads and is protected from attacks.
Our task was to: 1. Stable system for handling high loads; 2. Adaptation pool for any software; 3. Connecting any hardware for mining cryptocurrency Tkeycoin; 4. Fair remuneration calculation; 5. Security.
The main goal is for any user, regardless of the software and hardware used, to be able to connect to Tkeycoin mining via a pool. The first releases will be accompanied by a simple user-friendly interface, easy connection, instructions for various mining programs that can be connected.
In future releases, we will optimize the operation of the pool, add new features, as well as tracking functions and other nice things. any suggestions from miners and the community are interesting to us and will be implemented, so do not hesitate to send your suggestions after the launch.

TKEYSPACE updates


https://preview.redd.it/fjy2dkanwe151.png?width=700&format=png&auto=webp&s=99dedd6aa59ae7eb4d585d2ef1ddae4cc6dd50f9
Work on the TkeySpace mobile app is also not standing still. We will soon release updates for TkeySpace on Android and iOS.
This release is a complete transition to the most stable version of the mobile wallet. This means that after the update, even with the largest changes, the user will not need to completely reinstall or restore to use the new features, as before, just update the app via the AppStore or GooglePlay.
Between the previous update has been a sufficient amount of time, on average, updates are released once a month. This update will be one of the major ones. We are finishing work on the code to prepare the app for the new features that will be available this year. Besides, we are improving the app’s logic, data processing speed, optimizing the code, restoring order, and preparing for the global market.

Exchange, purchase of cryptocurrency and withdrawal to the Debit/Credit Card


https://preview.redd.it/1maxjrqowe151.png?width=700&format=png&auto=webp&s=cefd5bf1ec823049eeb25640c470024a41c0430c
In addition to pleasant optimizations, the app will display the exchange and withdrawal to a Bankcard, tab with an optimized page for exchange, withdrawal, and the purchase will be available directly in the mobile app. This upgrade will also capture the cryptocurrency exchange SWAP page, which can be evaluated after the update. Other features and new features will be announced by the developers immediately after the release.

SWAP Update

The development team is finishing work on optimizing the SWAP service. Regardless of updates, it is available in working mode 24/7/365. The team is working on improving the operation, optimizing the page, changing the interfaces, improving navigation, and speeding up query processing. This update is also among the upcoming ones, along with the pool, mobile wallets, and other news that will excite.

Network Statistics

In the network statistics section, there are several sections that will be fixed — this is the hash rate of the network and the volume of Tkeycoin. Now the volume of Tkeycoin is displayed by mTKEY, and the graph itself indicates M TKEY, the user may incorrectly understand the volume of transactions in the network, so, given the current volume, it is advisable to switch the display to TKEY, and in the future switch to mTKEY for large volumes.
TKEY is divided into cryptograms (CryptoGramm, cgr), uTKEY (keys), and mTKEY. 1 TKEY = 100 000 000 cryptograms. 1 mTKEY = 100,000 cryptograms. 1 TKEY contains 1000 mTKEY. 1 mTKEY = 0.00100000 TKEY 1 uTKEY =100 cryptograms 1 TKEY contains 1,000,000 utkeys. 1 uTKEY (keys) = 0.00000100 TKEY 1 cgr = 0.00000001 TKEY

Cryptocurrency Exchange

This issue has become the cause of mass discussions, disputes, investigations, the subject of memes, kitchen, and online conversations, that just did not happen, that TKEY is not taken anywhere, someone made guesses that we are waiting for everyone to run away, or TKEY is a world conspiracy and around some actors, you can write a book or shoot a great series, not worse than Breaking Bad.
Jokes, jokes, but the question is serious. Since the 4th quarter of last year, the company has been actively working on the issue of listing, prepared the necessary platform for this, held several meetings, negotiations, released the necessary products, figured out various transfers of funds to the blockchain, worked out many small things, many major issues that were behind the scenes. Everything is ready, and it’s time to start soon. This will be a surprise, believe it or not, and we will meet you on the stock exchanges :)

What other plans does the company have?

Enabling payment at retail outlets

After entering the exchange, we will actively engage in connecting payments to implement them and link them to TKEY. The plan, strategy, and legal component are ready.

Payment development

This implies the development of payments and services that will expand the use of digital currencies in the commercial sphere. Application on the territory of Russia will depend on the Federal law on the CFA, in any case, we plan to analyze the law, after its release, to find a legal way to implement payments based on blockchain and digital assets. Therefore, until the law is released, we are keeping this initiative in the future, and we will work on other jurisdictions that will support it.
We left some plans behind the scenes, because they will make the greatest impact on the market and the value of our asset, and this — likes silence.

What useful materials will be released soon?

How to effectively use the SWAP service together with the exchange and purchase of cryptocurrency from a Bank card?

We will tell you in detail how to use these 2 services, how to save on payments and purchases, how to exchange tokens that are very difficult to exchange, how to quickly get money for them to the card, and much more.

The law CFA

Our opinion about the law of cryptocurrencies in Russia, what to pay attention to, what to prepare for, how to act if there is a complete ban. Let’s talk about legal nuances and banking practices.

TKEY blockchain

In this material, we will talk about the blockchain, analyze the issues of the system, expand the questions on attacks, payment processing, and touch on the system of multiple chains. The article suggests your suggestions, perhaps someone will have ideas that we will implement in the chain.
At the end,
Don’t forget to ask questions in the comments or send suggestions to [[email protected]](mailto:[email protected]) we will be happy to respond and consider your requests for any of our services. Collaboration, feedback, help us make the whole platform better.
Thank you for being with us! Until new meetings, stay tuned for news, updates, because the most unexpected news comes spontaneously.

[Tutorial] Build and run your own Bitcoin node on Ubuntu 19.10

I am finally doing my part and running my own bitcoin node in a small home server.
Most guides I found online were either incomplete, outdated, or explained only how to run bitcoin-qt (graphical interface). So I built a minimalistic guide with the starting point of Ubuntu 19.10 to run the latest Bitcoin core release (v0.19.0.1) as of today.
If you have an old laptop (raspberry pi, NUC, etc even better) a reliable internet connection, and ~ 500Gb of HDD (USB external drive are just fine), you should consider running a node. It's fun, you will deepen your computer knowledge, and you will be supporting the network.
A GitHub gist with just the code: https://gist.github.com/Koff/1638aca30d6e14f1dcd374825018074a

Crypto Faucet I use to store my mined bitcoin on, with 4.08% APR paid daily with accounts over 30k satoshi. Referral link included, I share 50% commissions with my referrals paid every Sunday if you're interested.

My referral link for the aforementioned FREEBITCO.IN: https://freebitco.in/?r=30437643&tag=redditF
I have cross referenced this post on my site: passivecryptoguides.com
Why should you sign on with me? I'm not a one off, you can reach me personally through DM or post comments. I've done most of the leg work, alleviating the trial and error process. Just follow the steps in this guide specifically in sections 7️⃣, 8️⃣, and 9️⃣.
I share 50% commissions, get a kick back on everything you earn weekly.
I trust this site, and personally have 270$ worth of bitcoin in one account with almost 500$ total including two other accounts.
Coming from Cointiply? Well, as a heads up, you're not actually holding any BTC. I suggest what you earn you HODL in FREEBITCO.IN.
Just some abbreviation and terminology explanation before we start for those unfamiliar.

1️⃣GENERAL INFO1️⃣
FREEBITCO.IN can be accessed from any device with internet.
Using a VPN or a TOR is now allowed given that your account achieves certain criteria similar to a captcha free account requirements.
🛑WARNING: FREEBITCO.IN wipes inactive accounts after a certain period! If you lose interest, withdraw your BTC!
📝NOTE: iOS devices (iPad, iPhone) are restrictive. The only way to access is via website, as BitBot isn't available.📝
FREEBITCO.IN is what's called a "faucet", a site that gives a small steady stream of crypto which FREEBITCO.IN does through hourly rolls and interest accrual.
FREEBITCO.IN also hosts other means to win or earn crypto, you can gamble with Multiplier, or bet on world evens and crypto prices.
After your account reaches 30k Satoshi, you begin to collect interest. The site also offers lifetime referral commissions, explained later in this guide.
All you need to start is an email. You can add more verification options for security later on. I would highly suggest it. Use a junk email though.
2FA and MFA are strongly suggested. A password should be 15 characters long. I suggest Google Authenticator for your 2FA needs.
I know you can definitely access this site from Brave Browser with add blockers enabled. I'm sure it will work with others. Even without an ad blockers, they only advertise their site gambling and games, no 3rd party adds that I've seen. It's not too invasive or spammy either.

2️⃣POST INTENTIONS2️⃣
This post is both an advertising platform I use, and a guide I've made to help those interested to automate and optimize earnings.
For those of a cautious mindset, I've uploaded all of FREEBITCO.IN's information on interest accrual, security, and proof of mining on Imgur, in case you're worried about visiting the site.

3️⃣MY EARNINGS3️⃣
So at this point, with hourly claims and daily interest, I'm bringing in roughly 8978 Satoshi (or .70$ USD with BTC at 7804$ USD) daily at full optimization on one account, and two other self referred accounts without lifting a finger. This is before the fact that a hourly roll (claim) can reward up to a max of 200$ USD worth of BTC (percentages in section 5️⃣).
They also have a weekly lotto (tickets awarded with every roll and referral roll) with the last 1st place winner receiving .32769156 BTC (2587$ USD at current bitcoin price).
This is also not including my current commissions on accounts not owned by me. In this post I will describe some of my strategies I've incorporated, and some insight into how this website works.
To offload or withdraw bitcoin, you're going to need what is called a "wallet". I personally use Coinbase (available on mobile or desktop) as you can sell it through here as well and easily move money to Paypal or a bank.
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
4️⃣HOW DO COMMISSION REWARDS WORK?4️⃣
If you are already on FREEBITCO.IN, do you have someone who referred you? Do they share commissions? If not, why not make a new account and join me, where you'll get a return on everything you earn.
As you can see, large affiliate groups don't share anything, hoarding hundreds of thousands worth of BTC earned off their referrals
I share 50% of my commissions. I get 50% of your roll rewards, 25% of your interest, and 0.4% of your wagers. All of this is paid out by FREEBITCO.IN as a commission, so it's not pulled from your rewards or held BTC.
So the more you're active, the more you'll receive from me weekly (being active is doing anything that I get commissions from). IMPORTANT: Your (and all referrals) shares are based on activity, so if you are inactive for the week, you get a lower % for that week. If you're the most active of my referrals you get a higher percentage of what I share. This is to incentivize being active and to stop people from getting a cut without doing anything.
If you have FREEBITCO.IN automated, you don't have to worry about this. However, having a larger bankroll to earn interest, or playing Multiply BTC (I do not suggest playing unless doing so to meet auto roll requirements) will increase can your activity further.
Commission Structure
Here is some proof, I've actually shared about 2/3 of all commissions
Commissions update 12 January 2020
Here is a proof of Payment section per individual

5️⃣SOME CLAIM STATS5️⃣
You can earn AT LEAST .00000552 BTC (.048$) daily when automated (or claiming every hour on the hour) before bonuses (like using reward points to increase rewards 1000%). After some testing, it seems that this amount will always be about .048$ worth of BTC, base claim rewards no bonus active.
After .00030000 BTC, you accrue compounding interest at a rate of 4.08% APR, paid daily. As soon as your daily interest is accredited, it too starts earning interest. The daily interest rate comes out to ~0.011% of your total held BTC.
FREEBITCO.IN gives you a roll once every hour, free
📝NOTE: Roll rewards fluctuate inversely with BTC price. BTC goes down, roll rewards go up, vice versa. The BTC rewards USD value will be extremely close to the values represented below.📝
Current rewards and probability with every hourly roll.
(.002$) -> 98.85%

6️⃣MULTIPLY BTC STRATS AND INFO6️⃣
🛑!WARNING!, NO STRATEGY IS 100%, THE MULTIPLIER GAME IS GAMBLING, YOU CAN STILL LOSE YOUR WHOLE BALANCE IF YOU PUSH YOUR LUCK.🛑
UPDATE: I decided to do some research after some odd outcomes when extensively testing some of my Multiplier strats. Turns out FREEBITCO.IN does indeed have a house advantage that isn't too transparent. Longer sessions are almost always going to come out negative. If you still plan on playing, do short sessions, once daily max, with lower amounts.
There are a couple methods to play the Multiplier with a reduced risk (but still a risk) here as well. I would suggest small play sessions.
STRAT #1
My preferred settings for AUTOROLL on MULTIPLY that I've had the best success rate with to date. (preferably with .00005000 in ACCT for best results)
BET: Minimum
ODDS: 3
ROLLS: (doesn't matter, 100)
BET ON: alternate
STOP BETTING PROFIT: .00000050, important as the bets will get exponentially higher with every loss. Win in small increments.
STOP BETTING LOSS: Set a loss limit if you want, I have mine set to .00001 and haven't reached it
ON WIN: select increase bet 0%
ON LOSS: select increase bet 65%
RANDOMIZE CLIENT SEED: yes
DO NOT REFRESH: yes
Here is a pic of the settings
Anything else doesn't matter. Make sure the boxes are checked for the above options.
With this strat, I've won positive on one account, about .000077 BTC, and I've only played 5 or 6 times, at less than 2-3 minutes of play time a session.
STRAT #2
Good for accounts with a low balance. I've had a surprising amount of luck with this method, enough so that I thought I'd post it here with an update. This could work well for accounts with less than 1k Satoshi, as a losing streak wouldn't be a huge loss. For this strat, you should have at least 189 Satoshi in your account.
BET: Minimum amount
ODDS/WIN CHANCE: 189 or %0.5
ROLLS: 189 (remains the same no matter if you bet more)
BET ON: High or Low, but not Alternate.
STOP BETTING ON PROFIT: Minimum amount, once again, you want continuous small wins
UPDATE: Conducting more tests for viability
I played these settings 10 times, I came out positive 8/10 times. In the end I was positive 433 Satoshi total with selecting "hi".
On selecting "low" I went positive 5/10 losing 525 Satoshi.
On selecting "hi" and betting 10 Satoshi, I went positive 3/10 times losing 9708 Satoshi.
On selecting "high" and betting 100 Satoshi, I never went positive, 0/10. Losing 189000 Satoshi (~15$ USD).
There does seem to be a pattern of losing more when betting more. Like anything gambling, there's probably a house advantage that's not too transparent.
Win small lose small.
Pic of these settings
STRAT #3
Another strategy I've tried is betting most of my balance once occasionally with a 94.06% chance of winning. This is, eh, alright to risk OCCASIONALLY, but a loss would set you back more than you ever made using this strategy, which happened to me, I lost about 40 USD worth of BTC after making maybe 5 USD.
THIS METHOD IS GREAT FOR MEETING NON-CAPTCHA ACCOUNT REQUIREMENTS!
Playing this in auto roll, out of 20 rolls I'd always lose at least once, putting me into the negative. Even with 10 rolls, I'd more often then not lose at least once.
Pic of these settings
There are other strats out there, such as the "Martingale", which is essentially doubling the bet amount every loss, then resetting your bet to minimum after a win to in theory "win back what you lost". At 47.5% odds of winning, I've had loss streaks that would drain my account.
My summary for Multiply, use sparingly. Don't use it as your primary means of earning. Use once or twice daily, limit play sessions to 5 minutes max.
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
7️⃣AUTOMATION7️⃣
📝NOTE: FREEBITCO.IN captcha requirements seem to be tiered, with requirements for Captcha free upscaling when you BTC holding passes a certain threshold.
I'm currently testing, as is another team member (Shout out to u/SrExtreme69) , what exactly these thresholds, if holding at these thresholds increases the length of Captcha free rolls, and at what amount does FREEBITCO.IN no longer require these to be met.📝
📝NOTE: To start automating, remember to verify email and setup 2FA or the Captcha will still appear even if your account meets Captcha free requirements. Check the site occasionally as Captcha free roll requirements can change. After certain held BTC amount you don't need to renew your requirements. I haven't had to achieve new requirements in over a month.📝
📝NOTE: You may need to manually roll for a bit until the the ability to achieve a Captcha free account becomes available. It doesn't show at first.📝
📝NOTE: It's very difficult, if not impossible to automate on iOS devices.
First of all, getting to this point can be a grind, but once achieved you'll have a steady flow of BTC with options to increase earnings through rewards claims using RP. I would suggest going to your PROFILE tab on FREEBITCO.IN and disabling lottery to increase RP production when starting out. Using other apps or resources to supplement income is a good idea as well.
On the FREE BTC page, there is a blue text hyperlink with requirements that need to be met to make your account captcha free, thus allowing you to enable autoroll on extensions or apps. It has multiple ways to achieve this and they can change, so if your autoroll has stopped, check to see if these requirements have changed.
Here are the requirements. (Amounts vary)
It seems only two of these requirements need to be met.
The less risky and easiest method is to buy lottery tickets and bet with jackpots on. Even better is depositing bitcoin if you have that amount.
The POSSIBLY least expensive method is to bet both regularly and with Jackpots enabled on MULTIPLY (for higher amounts required, IMO Multiplier strat #3 works best)
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
8️⃣OPTIMIZATION AND USE OF FREEBITCO.IN8️⃣
For computers
I would suggest using Firefox, as you can add functions and tools to your bar up top. One of the being a "auto roll" for FREEBITCO.IN, still requires a "captcha free" account. Turn it on and let go, check it occasionally to make sure its still going.
Autoroll firefox add-on link
My link again for ease of access
Not my preferred method, but good for a second account, as using a computer means devoting more attention to FREEBITCO.IN in an inconvenient manner if you are just starting out. After Captcha has been removed, this becomes more hands free, but not as profitable as using bitbot, as you can't autoclaim RP rewards.
I haven't tried many methods besides using Firefox addons, as I'm wary of sources or intent when it comes to 3rd party scripts or programs. If I find any trustworthy scripts or programs, I will update here.
For Mobile
🛑BITBOT WARNING, IF YOU USE BITBOT TO ACCESS FREEBITCO.IN BEFORE USING MY REFERRAL, YOU WILL BE REFERRED THROUGH BITBOT, AND THEY DON'T SHARE COMMISSIONS AS FAR AS I CAN TELL🛑 My Link again
📝NOTE: iOS devices (iPhone, iPad) do not have access to BitBot, nor do they allow extensions/add-ons on their browsers. I have not personally found a way around this. You may still access the site and manually roll.📝
I use BitBot. This is the best place to start from IMO. You can set it to notify you of rolls and gives direct access to the site from the app (you can also access the site from any device with internet). Once your account is "captcha free" you can set it to auto roll AND automatically claim rewards every 24 hours (RP increase, BTC increase, Lottery ticket Increase).
📝NOTE: Bitbot allows auto roll from the app for accounts over 500 RP. This isn't permanent, as it uses your RP. You'll need to log onto the website through a browser to achieve captch free account requirements, which Bitbot does recognize, which allow completely free rolls.📝
📝NOTE: Accessing FREEBITCO.IN through BitBot doesn't allow access to the Hi-Lo or betting games.📝
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
9️⃣STRATS TO INCREASE EARNINGS9️⃣
Bitbot optimization
I started manual claims by setting roll notifications to "ON" for a while until I supplemented my BTC in FREEBITCO.IN with what I was collecting from my miner and CryptoTab. Once I was able to AUTOMATE and I had enough RP to claim the RP BONUS, I set it to do that automatically every 24 hours as this nets more RP than you spend (EG, 100 RP roll bonus costs 1200 RP, but can net 2400 RP if claimed every hour). Eventually you accrue enough RP to claim the %1000 BTC bonus, probably at a rate of once or twice a week.
My current BitBot settings now that its auto claiming, I have the 24 hour auto bonus claiming 100 RP roll bonus and 100% claim bonus, spending a total of 1520 RP, but I'm making 2400 RP with the RP bonus, leaving me 780 RP in the positive each day. Every now and then I'll stop the auto bonus claim so I can buy the 1000% claim bonus (3200 RP). So on a normal day I'll make about 1344 Satoshi. Bitbot auto bonus settings
Once your accrue more referrals, or save enough RP, it's possible to claim the 1000% BTC roll bonus multiple days in a row. This is just about as optimal as you can get for auto rolling.
Self Referrals
If you have two devices (phone and computer preferably) you can make two accounts as long as one uses a different wifi or internet connection, as the roll rewards tracks IP addresses for roll counts. So if you have 2 devices on the same network, it sudo links accounts, so if you roll on one, it restarts the timer on the other. This allows you to collect referral rewards from yourself. Effectively adding 25% of interest and 50% roll rewards.
I currently have a phone autorolling on BitBot with a computer autorolling on Firefox with a tool to roll automatically as long as the page remains open. My computer account is referred from my mobile account, and is currently bringing in an extra .000015+ BTC weekly (currently, total will be this Sunday and I will update).
I've also made another account on my partners phone, linked it with bitbot and got it auto-rolling. Once bitbot is going, its non-invasive and you can silence notifications, it also uses minimal data.
Supplementing with CryptoTab
I'll use CryptoTab on my computer 24/7 to earn BTC from that while I have FREEBITCO.IN running. I also have it running on my phone at night when I sleep and on an iPad I have that I don't use much, its server mining, so no worries about battery on mobile devices. On computers it does actually use your processing power. You can directly deposit into you FREEBITCO.IN accounts.
CryptoTab Link
I've used it for two weeks and have earned a total of .000454 BTC (3.60$ USD). Not huge, but enough to start collecting interest on FREEBITCO.IN and to get the capthca free account requirements.
Supplementing with Cointiply
🛑WARNING: Cointiply's main currency is the constant, weighted against the dollar (10,000 coin/1USD). This means your actually BTC holdings will fluctuate with BTC's price.
For this reason, it's my strong opinion that DON'T HODL in Cointiply as you're not holding actual BTC.🛑
Cointiply is a great site to earn decent amounts of COIN which translate to SAT's. Earn coin, withdraw to FREEBITCO.IN (as you actually hold BTC in cointiply).
I also use an ASIC miner (Antminer s9i, DIY liquid cooled and overclocked with BixBit firmware), and whatever I earn I'll put that into FREEBITCO.IN to collect interest. If you want, I may be willing to do a rental.
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
1️⃣0️⃣ADVERTISING YOUR LINK1️⃣0️⃣
📝NOTE: Since this faucet has been around a while, many people privy to sites such as this are already signed up. So getting referrals can be a slog. My tips for your ads is be genuine and don't hard sell or post "too good to be true" sensational ads.📝
COINTIPLY
This is another faucet. Its structure is a bit different from FREEBITCO.IN, as you complete offers to earn coin. Within this site (also an app) users can earn coins by doing PTC ads (and other offers), this is a good method to get exposure as you can advertise as well. Using this method my traffic for last week as about 800 people.
13000 coins buys about 1000 "clicks" on your ads. They also have options to advertise to people based on location (these options will increase or decrease cost). After your first ad, you usually get a 10% off coupon good for 7 days as well.
You can earn this amount within a day doing surveys on Theorem. I've done surveys before, and this has to be one of the best surveys sights I've ever done. Very rarely do I get kicked out mid survey, and if I do, I still get partial pay.
I will also use "Hideout" on my computer and leave it running. It has to be the open tab on your browser, with the browser open, not minimized. Let it go and check it occasionally as it has a timeout at roughly 2-3 hrs idle. As of now this is the best passive method of earning on Cointiply.
PI NETWORK
Pi Network, an ICO (Initial coin offering) based on trust and social media is another good medium for advertising. I will usually see 15-20 people click on my link with 2-4 ads posted per day.
Just go to "chat", select "random" and post an ad in the chat channel. No charge.
My tip, keep your ads short to medium in length, don't spam.
XYO NETWORK/COIN APP
This is another crypto earned through "geo-mining". On the "coin" app you can do a "geodrop" where you can leave a note. Just click on the box with a parachute icon, select "any" on the "Tile" selection. Leave your ad in the "note" section.
It costs 10 "COIN" at the very least to do a "geodrop". This method may not be worth it if you aren't already involved in the program. To earn a substantial amount of coin, you'll need a subscription or a "sentinel". Sentinels can actually be purchased for under 20$ nowadays (depending on site) and is the best option to earn. Without these you'll only make approx .05-.18 coin every 30 seconds if you're actively moving.
My tips if you plan on advertising on this platform, once again keep it short, and only advertise around 7-9am and 4-6pm, as this will be peak mining hours with people driving to and from work.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

The outbound connection limit is exactly 8, the inbound connections are only limited by the -maxconnections total which is usually 125 (version 0 .3.25). – Stéphane Gimenez Sep 2 '11 at 22:21. 1. Thanks! It helped me realize my router had UPnP off. *facepalm – user173 Sep 3 '11 at 7:15. 2 @EvilSpork is right. For easiest solution use UPnp. For the manual but much safer solution use port ... 1. Install Bitcoin-Qt Since version 0.9, Bitcoin-Qt was renamed to Bitcoin Core t o reduce confusion between Bitcoin-the-network and Bitcoin-the-software. Bitcoin Core is a full Bitcoin client. It is a thick client, meaning it requires the full blockchain (explained below) on local disk to operate and expose blockchain back to the network to help relay and verify transactions. Since 0.14.0 the approximate transaction fee shown in Bitcoin-Qt when using coin control and smart fee estimation does not reflect any change in target from the smart fee slider. It will only present an approximate fee calculated using the default target. The fee calculated using the correct target is still applied to the transaction and shown in the final send confirmation dialog. 0.14.2 ... There are two variations of the original bitcoin program available; one with a graphical user interface (usually referred to as just “Bitcoin”), and a 'headless' version (called bitcoind).They are completely compatible with each other, and take the same command-line arguments, read the same configuration file, and read and write the same data files. When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
