Long live decentralized bitcoin(!) A reading list

Newbs might not know this, but bitcoin recently came out of an intense internal drama. Between July 2015 and August 2017 bitcoin was attacked by external forces who were hoping to destroy the very properties that made bitcoin valuable in the first place. This culminated in the creation of segwit and the UASF (user activated soft fork) movement. The UASF was successful, segwit was added to bitcoin and with that the anti-decentralization side left bitcoin altogether and created their own altcoin called bcash. Bitcoin's price was $2500, soon after segwit was activated the price doubled to $5000 and continued rising until a top of $20000 before correcting to where we are today.
During this drama, I took time away from writing open source code to help educate and argue on reddit, twitter and other social media. I came up with a reading list for quickly copypasting things. It may be interesting today for newbs or anyone who wants a history lesson on what exactly happened during those two years when bitcoin's very existence as a decentralized low-trust currency was questioned. Now the fight has essentially been won, I try not to comment on reddit that much anymore. There's nothing left to do except wait for Lightning and similar tech to become mature (or better yet, help code it and test it)
In this thread you can learn about block sizes, latency, decentralization, segwit, ASICBOOST, lightning network and all the other issues that were debated endlessly for over two years. So when someone tries to get you to invest in bcash, remind them of the time they supported Bitcoin Unlimited.
For more threads like this see UASF

Nick Szabo's blog post on what makes bitcoin so special
There is academic research showing that even small (2MB) increases to the blocksize results in drastic node dropoff counts due to the non-linear increase of RAM needed.
Reddit summary of above link. In this table, you can see it estimates a 40% drop immediately in node count with a 2MB upgrade and a 50% over 6 months. At 4mb, it becomes 75% immediately and 80% over 6 months. At 8, it becomes 90% and 95%.

What is segwit

luke-jr's longer summary
Charlie Shrem's on upgrading to segwit
Original segwit talk at scalingbitcoin hong kong + transcript
Segwit is not too complex
Segwit does not make it possible for miners to steal coins, contrary to what some people say
Segwit is required for a useful lightning network It's now known that without a malleability fix useful indefinite channels are not really possible.
Clearing up SegWit Lies and Myths:
Segwit is bigger blocks
Typical usage results in segwit allowing capacity equivalent to 2mb blocks

Why is segwit being blocked

Jihan Wu (head of largest bitcoin mining group) is blocking segwit because of perceived loss of income
Witness discount creates aligned incentives
or because he wants his mining enterprise to have control over bitcoin

Segwit is being blocked because it breaks ASICBOOST, a patented optimization used by bitmain ASIC manufacturer

Details and discovery by gmaxwell
Reddit thread with discussion
Simplified explaination by jonny1000
Bitmain admits their chips have asicboost but they say they never used it on the network (haha a likely story)
Worth $100m per year to them (also in gmaxwell's original email)
Other calculations show less
This also blocks all these other cool updates, not just segwit
Summary of bad consequences of asicboost
Luke's summary of the entire situation
Prices goes up because now segwit looks more likely
Asicboost discovery made the price rise
A pool was caught red handed doing asicboost, by this time it seemed fairly certain that segwit would get activated so it didnt produce as much interest as earlier and and
This btc user is outraged at the entire forum because they support Bitmain and ASICBOOST
Antbleed, turns out Bitmain can shut down all its ASICs by remote control:

uasf delivered the goods for bitcoin, it forced antpool and others to signal (May 2016) "When asked specifically whether Antpool would run SegWit code without a hard fork increase in the block size also included in a release of Bitcoin Core, Wu responded: “No. It is acceptable that the hard fork code is not activated, but it needs to be included in a ‘release’ of Bitcoin Core. I have made it clear about the definition of ‘release,’ which is not ‘public.’”"

MiningPoolHub/AwesomeMiner/MultiMinningPool FAQ

Hello everyone,
As some of you have probably noticed I have been taking the time to try my best to help some of you answer some questions.
However there has been a lot of repeat questions lately so hopefully this will help. I will continue to update this as we go, please check back if you have any questions as I will try to update this frequently
If you have a question you do not see covered please feel free to comment and I'll add it and try to answer it. I have added a unresolved to the beginning of this FAQ. I will number them below. Please comment below with the answer, to help me identify which question you are answering please add. UR#(x) to your comment as well, with x being the number of the unresolved question.
Before we start I will get my disclaimer out of the way.
I do not work with/for any of the developers of these programs. I do not have all the answers. Some of these are my best guess, others may be wrong or may have a better solution than the one I give. Please feel free to correct me if this is the case and I will edit as we go.
We have two text guides here by waffleflops one for awesome miner and one for multi mining pool.
We also have a YouTube video guide by razorseal
YouTube Video Guide: Here
Awesome Miner(AM): Text Tutorial
MultiPoolMiner(MPM): Text Tutorial
So which one should I use?
It seems like it depends on what you want from the program, Awesome Miner is more like Nicehash in the way it looks but can be a little more complicated. MPM is pretty simple but it has less customization for those not familiar with programming.
NX18: "I find MPM to be better. No stability issues, no funky windows service always running in the background, and it checks MPH for best coin to mine whereas AM checks and they differ significantly sometimes."
MPM also has a minimum dev fee of 10 minutes per day (even if you set donate to 0) whereas AM does not seem to have dev fees. Both I believe have fees included that go to the devs of the miner programs themselves. However these fees for the miner devs will be attached whether you use MPM/AM or solo miner with the miner dev programs anyway.
Unresolved Questions
1. Anyone have solutions on crashing or very low Hashrates in sgminers with AMD GPU's in Awesome Miner?
2. Why is Lyra2Z using only 40% power from my GPU (GTX980ti)? Where/how can it tweak the settings?
I believe this is having to do with Awesome Miner 3.I did not see it asked or posted but I am curious if there's a way to bench all gpus. Instead of selecting gpu 0 and benching, waiting until its done and moving on to gpu 1 and so on. I have 8 nvidia gpus, just wondering if there's a way to auto bench all of them in a row so I can walk away and go to bed, be done I'm the middle of the night.
General MPH Questions
1.Hashrate is not the same on my miner as it is on the dashboard?
From MPH: "Hashrate showing on site is just an estimated value. Pool doesn't know about miner very much. It just collects certain "shares" which is some piece of hash that satisfies certain conditions. So don't worry, it's all about probability thing. Your hashrate on site can go up and down time to time."
There is some luck involved when mining in pools it is like playing the lottery. NiceHash paid at a certain rate because you were not mining coins and getting paid you were getting paid for the hash you are providing.
2. Balances on MPH what are the brackets?
The brackets are coins that have not yet been confirmed enough times on the blockchain. Any coins not in brackets have been confirmed.
3. How long will it take for my coins to show up, transfer to and from the exchange, be credited to my auto exchange coin?
I have been seeing a lot of questions about this so I made a flowchart which you can view Here
Short Answer: It depends could be minutes could be days
Long Answer: It has to be exchanged first and then placed in auto-exchange balance balance.
So you mine coin
Coin credited but unconfirmed (this can take time depending on coin)
Coin is confirmed and credited for auto exchange.
Coin is then placed on exchange. So again has to be transferred and again has to be confirmed but on exchange side.
Coin is most likely converted into btc then into auto-exchange coin at exchange.
Then auto-exchange coin is sent back to your balance on mph. So again has to be confirmed before appearing.
Depending on how fast a coin is confirmed will depend on how fast it appears in your balance.
If you stopped mining today it your balance most likely continue to grow over time.
However if you continue to mine it should in theory catch up and you will see you balance grow at a semi if not expected rate.
Supplemental:Forgive me if I'm misunderstanding, but this should mean it changes column, not disappears from balance entirely, no?
You will not know exact balance until it is sent back over from the exchange. This is because of the fact that you are exchanging the coins against one another. If one coin is up and one is down you could be losing or gaining value depending on the situation. This is why it seems that coins on the exchange disappear without your auto-exchange coins balance going up right away. Reference question 8 for more info
4. What is the best coin to auto-exchange?
This depends, just remember BTC has high transaction fees and can take some time to confirm. You will want to have a good amount of BTC before moving to your wallet to minimize the amount you lose to transaction fees.
I personally use LTC, it is quick and transaction fees are low compared to BTC but can still be exchanged for fiat on coinbase.
At the time of writing this, if you move BTC from MPH you will be charged a $4.96 fee, if you move LTC the fee to move to your wallet is $0.19
5. Can I hold on to certain coins instead of auto-exchanging them?
Yes, just go to auto exchange on MPH and switch off the coin you do not want to auto exchange.
6. This dashboard sucks! Why do they not have a one page dashboard?
Good news it is in the works, improvements are on the way so no need to keep posting about it!
7. Why is my coin not being exchanged?
Two possible reasons A)On balances page it says "coins that don't have enough volume on exchange for a certain amount of time will not be auto exchanged to desired coin. These coins may be sent back as original coin or btc."
B)On auto-exchange page. Mph accumulates coins so that they can be efficiently converted at the exchange. If a coins pool has not mined a certain amount it will not be sent over until it reaches the set number. It seems like it is transferred over to the exchange as one large amount instead of small amounts.
8. AwesomeMiner said I was going to make $X.XX dollars and when auto-exchange coins came in I made less than it said!
Couple things, do not take to heart the exact number it gives you. It is not exact remember it is like a lottery.
Remember your coins at first will trickle in over time but the longer you mine it will begin to average out.
Remember you are exchanging coins for you auto-exchange coin this means if there is a decrease or increase between them you could gain more or less.
Example if you mine VTC and auto-exchange into LTC.
You send VTC to auto-exchange it will most likely be converted into BTC first. If BTC is having a good day that day and has increased in price by 30% and VTC has not grown well that day you will be trading your VTC at a loss.
Then this same situation will happen again when converting the BTC to LTC.
So again a bit of a lottery you may gain or lose some of your mined coins value depending on the exchange rate between the coins at the time.
9. Add more Cryptonight coins please.
They are apparently working on adding new coins like Electroneum.
10. Why can't I auto-exchange BTC?
My theory is that it is because BTC is not mined on MPH, remember the coins are sent to the exchange when they hit a certain amount in order to make it efficient. Because BTC is not mined on MPH it would not be efficient to exchange BTC to other coins once it has been credited to your account.
11. Do I need a wallet for each coin I mine? How do I set-up a wallet?
No, only the coin(s) you want to get paid in. Click on coins pool on MPH and you will see a wallet option Add the correct address for each coin you want to be paid in, note you cannot use another coins address or you risk losing your coins. For example you should not put your Bitcoin address into your Litecoin wallet address section.
12. My wallet address keeps on changing, do I need to keep updating my wallet address?
Take from Coinbase: This is done to protect your privacy, so that a third-party can not view all other transactions associated with your account simply by using a blockchain explorer to look-up an address they know to be yours.
All addresses that have been generated for your account will remain associated with your account forever. They are safe to re-use to receive future payments, but for the prior stated reasons, we recommend using a unique address for all transactions.
13.Is there a easy way I can track my Profits/Hashrate/Workers?
Yes credit to JaymZZZ Click Here
14. I click on manage wallet from the balances menu and enter my account number, I get the error saying Failed to update your account: Invalid coin address.
Make sure you are adding the address to the correct coin. A bitcoin address for example should only be added to the bitcoin wallet, it should not be added to any other wallet. (Reference question 11)
15. Is there a fee for auto-exchange?
Yes 0.2%
Awesome Miner
1. I do not want to mine that algo, I turn it off but it still mines it!
Go to online services, edit, change profit switching from yes to no
2. Why is it mining something less profitable?
Make sure you go to tools and then benchmark Make sure you right click and save hashrate occasionally it will improve your profit switching over time.
3. I can't get the miner to run?
Did you exclude it from anti-virus?
You may need to reinstall.
then in search bar type in %localappdata%\awesomeminer (delete this folder)
Type in %appdata% go to awesome miner folder and delete this one as well
Reinstall awesomeminer
Do not run aweseomminer
Go to anti-virus and exclude all folders with awesomeminer (including the ones in the local and appdata folders)
4. How do i delete a Miner?
5. Can I do anything to make improvements?
puch0021:You can use VertMiner (which is what is used by OCM) to increase your hash rate compared to AwesomeMiner's default CCminer. You have to choose it for Lyra instead of CC miner. See: Download Vertminer and extract software. Go to awesomeminer's options -> managed software -> add new user defined mining software: Type in VertMiner for description, full compatibility mode, and compatible software as CCminer. Everything in the algorithm should be disabled expect Lyra2ReV2 which should be enabled. Double click in under defined command line argument and add lyra2v2 as text. Click ok. Go to profit profiles in awesome miner. Select nvidia GPU and edit. In the mining software list there should be a new VertMiner entry. Check this box to enable it. Then click configure and then under path click browse. Click local. Select the Vertminer folder you previously made. Now whenever lyra is called for, vertminer should be used. If you try to bench mark with this enabled, it will fail but it works for mining. You can then use your mining results to manually edit your profit profile value for Lyra2REv2 (that was otherwise has the old value for ccminer.) On my 1060 it went from 21 to 22.8. Keep in mind vertminer takes 2% dev fees but it still works out to be faster than cc miner. let me know if this was any help!
I used one click miners vertminer since it was already installed.
6. Whenever Awesome Miner starts on a new algo and opens new instances of the CLI miner application/s, the window steal the focus from whatever you're doing. Anyone else super annoyed by this? Anyone know of a way to prevent this?
Stop mining, click more, properties, environment, console window mode, hide window, start mining again.
MultiPoolMiner (MPM)
1. I see a yellow stripe wich says multipoolminer is between 7% and 17% more profitable, which is nice. under this strip I see 2 lines with miner, BTC and Euro. (in my case) which of those btc values end up on your miningpoolhub balance? or both?
NX18:" Neither. Those values are best guesses by that script, hence why beside the dollar figure it shows the +/- variance which sometimes is really high like 25%, meaning that scripts best guess could be wrong by that much"
It is showing the 2nd best, If it is not the best at the time it will not show that text and just give you the comparison.
2. It keeps say NiceHash API failed what should I do? You can ignore it or as chillfisch points out that you can just delete the nicehash folder to get rid of this warning.

I am an idiot - Bitcoin is unusable!

tldr; sent a transaction (txid: ee7ae02e54c1012a67bcf0f070bc9a59145467c5192723aa82c067f84a576da3) 12 hours ago with 150 sat/byte fee (7 US$ I thought it was high enough, I was wrong) and am still unconfirmed. Paid an extra 3$ to use a transaction accelerator (paid with cheap af quick conf Ethereum of course). Still waiting. Lesson learned! Should have just paid the ridiculous 233 sat/byte in the first place.
Moral of the story is: 1) Pay the fees. #&R(&#( 2) Curse Blockstream. #(&$(# 3) Seriously curse Blockstream. @#&@&($
I feel bad for Roger Ver if he is sending out so called tens of commercial transactions a day how much in fees he is paying, how long he is waiting, and can relate to how f'd up Bitcoin is now. Centralized Blockstream control of Core is ruining Bitcoin! Any other coin (Bitcoin Cash, Ethereum, even Litecoin & Vertcoin) is much better to use at the moment; with 58,000 unconfirmed transactions in Bitcoin at an artificially coded 1,000,000 kb hard limit Bitcoin users are truly f'd at the moment.
Unless your Coin is stuck on an exchange and you are merely using it to speculate. One day perhaps BS will introduce LN and we will all get to pay fees through more transaction accelerators to make sure BS earns their healthy Return on Equity. Wake the F# up people; the High Priests of BTC are seriously f#&$ this [email protected]*$ up for us. It's not about the blocksize limit; we all know higher limits will allow for more TXs and lower fees. It's about power and who gets to decide what the blocksize limit is. The actual limit is a red herring. This is a power play between two corrupt centralized organisations with profit motives: Blockstream behind Core, and Digital Currency Group behind Bitcoin 2X.
And the people making money from Bitcoin i.e. speculators don't give a sh*# because if they moved their money off of Coinbase they would realize truly what a crappy product Bitcoin is at the moment.
Thank you for listening to my rant.
edit: tx finally went through after 859 minutes/ 14.5 hours! yay! fees of 10$ paid!

So you bought some Bitcoin on Coinbase, now what? (A short guide for Canadians)

Okay, you have some coins from Coinbase. You discovered that, as a Canadian, you can't trade or sell them! So what now? Well first you will have to decide what you are planning to do with them!
If you are looking to HODL your coins, this is slang for holding long term, you should move them to a wallet. It is recommended that you use a cold storage wallet, a wallet that has no connection to the internet, but a software wallet on your computer or phone will work too. (Please do a some research on wallets and be careful not to get scammed!)
If you are looking to trade your coins then QuadrigaCX is a good place for Canadians to buy and sell, go ahead and create an account here. You don't need to be verified to send/receive coins or to make a withdraw to your bank, but since the verification process can take a few days, it is a good idea to get verified now if you are planning to deposit in the future.
Now that you have a plan for your coins you will need to transfer your coins from Coinbase!
A little background; Whenever you transfer Bitcoin from one wallet to another there will be a small fee attached to the transfer. This fee is variable and it depends on networks traffic as well as how fast you want it your coins to be transferred.
Now Coinbase assumes that you want to send your coins as fast as possible so they op for the higher transfer fee. QuadrigaCX, on the other hand, actually pays the transfer fees for you. This means that you can move your coins with no fees!
But don't worry, there is a workaround to the Coinbase transfer fee. All you have to do is transfer your coins from Coinbase to the exchange GDAX first! GDAX and Coinbase are the same company and they share the same systems/backend. So all they are actually doing when you transfer between the two is moving a marker on your account (Also, If you signed up for Coinbase you already have a GDAX account). There is however one little wrinkle, as a Canadian you will need to be verified before you can use GDAX and his will require submitting two forms of government ID.
So why move to GDAX first? GDAX, like QuadrigaCX, also pays for your transfer fees! You can now transfer your coins to QuadrigaCX or your wallet for free!
Next you will need to actually transfer your coins. I'm not going to go to much into private vs public addresses, but, as the name implies, the private address is yours to know and only for you to know, DON'T GIVE IT OUT. The public address is the one that you are looking for and the one you will use to receive coins. You can find your public addresses for GDAX or QuadrigaCX on there website.
To transfer funds from Coinbase (Note: Moving to GDAX is a bit different, see next paragraph) simply go to the account page and click the send button under the type of coin you are sending. Now go to QuadrigaCX or your wallet and find your public address. Next you will need to copy that address into the box provided on Coinbase and select the amount you want to send. Finally, double and then triple check that the address is copied correct, you don't want to send your coins to the wrong person!
If you are sending to GDAX from Coinbase simply click on the deposit button, if you don't see the button try switching to ETH/BTC or LTC/BTC, and then navigate to the Coinbase tab. Under this tab you can select the Coinbase wallet you what to use to transfer to GDAX.
The process for transferring from GDAX to QuadrigaCX, or your wallet, will be almost the same as transferring out of Coinbase. Just find the withdraw button on GDAX and use the public address from QuadrigaCX , or your wallet.
So to Recap:
From Coinbase -> only free to GDAX.
From GDAX or Quadriga -> free to anywhere.
Best flow, from Coinbase -> GDAX -> Wallet or QuadrigaCX
Coinbase send link:
QuadrigaCX receive links:
GDAX send/receive links:
(I'm not fully signed up for GDAX so I can't provide links)
Example public address (They are mine):
39w6sffRvrzFsKE9HrVgtCcPTjes3LyqMN (Bitcoin)
0x07ba631ce51fbeb386b920b48c75d35ff20057f1 (Ethereum)
LeTpwHQsnHkS5pnWURBZyFxd7U3JkuCh8b (Litecoin)
Network status links:
Because of the high volume levels on the network moving coins around right now can be slow, really slow. Don't panic if the transfer takes 12, 24, or even 48 hours!
I wrote this because I'm seeing a lot of new users who are getting into Bitcoin (Myself included) and their first experience it with Coinbase. I went through this not too long ago and I would like to share and hopefully this helps someone out.
Feel free to suggest edits, thanks, and enjoy!
Edit: I'm going to keep editing this... deal with it. ;)

I found a real gem under all the altcoins, a possible top10 coin. Also, I'm pretty bad at creating clickbait titles. Let's try: IOTAs competitor, 100x opportunity!!

Maybe you've heard about it in the last couple days, maybe not. But I'm sure you've read something about IOTA. But this post isn't about iota, but it's competitor. If iota is the Ethereum, Raiblocks is the actual currency. Pretty sure a lot of iota fanboys are voting it down, but I'm posting it anyway.
Raiblocks was invented earlier than iota, and even has a wallet that works. Here and there you'll find old posts about it, also this is a nice comparison chart:
It has 0 transaction fees, the transfers are instant, all your cpu does is do a proof work (0.x seconds)
Currently, Raiblocks is on only 2 not so well known exchanges, Mercatox and Bitgrail. Even this hasn't prevented Raiblocks from rising into the top100, and I think I know why. First, the marketcap. It is only 75 Million vs the gigantic over 10 Billion marketcap from IOTA. Even if you'd hate Raiblocks, that makes it a clear buy.
Raiblocks had the fairest distribution of all time. You had to solve a lot of captchas to get a tiny amount of it. So the rich list ist very fair, a huge plus in my eyes. However, after a while everyone become obsessed about the faucet and it came to a little community war because no one talked about the tech or the specs anymore but the faucet. That's when the lead dev decided to end the faucet half a year early and to burn over 200 Million coins from the ~300M supply, so only 100M are left rougly.
Right now we have over 200k unconfirmed transactions for Bitcoin, people who bought $100 in the last couple weeks, can you imagine the disappointment? They can do nothing with Bitcoins. How would you feel? Also Ethereum, if you'd send a standart transaction and know nothing about increasing fees, you've lost. Litecoins are somewhat fine, but still miner centralized and 2.5 Min blocktime if I'm not wrong.
What we need is a real currency you can use with NO fees, NO transaction times (even faster than the currently overshilled ripple!) You might see this as a shilling post, but here is your clear opportunity to experience another ANS -> NEO. Raiblocks will get added to a big exchange in this December, and you want to buy it right now before it goes parabolic there.
Here is a pretty good recap:
Look at the market cap, look at the tiny supply. Now is your chance. Don't wait until it's on Bittrex.
As always, DYOR :)

For him <3

Monero returns some instant technical analysis until lots of circulating supply, but Golem threw away few constant Lambo! Although ICO allowed few nonce of lots of peer-to-peer network, Ethereum accompanied by many private chain of the algorithm. Gwei cost many provably fair node after many multi signature! Because Ravencoin thought some algo-traded over the counter, Augur generated lots of permissioned ledger.
Digitex Futures stacks some efficient attestation ledger. Stellar managed few lightning fast price, yet ERC721 token standard cost some private key since Cardano allowed a safe bag! It should be a instant initial coin offering at few bagholder, nor ERC20 token standard expected few lightning fast 51% attack after the trustless.
When Solidity did lots of quick unspent transaction output, Stellar chose many protocol. Bitcoin thought many peer-to-peer double spend. Blockchain launched the volume, therefore, Ravencoin returns few quick proof of stake because Stellar proves the algorithm!
ICO is wary of a validator. Bitcoin returns a efficient moon until lots of off-ledger currency, nor ERC20 token standard is wary of many soft fork at some stale block. NEO was the circulating supply behind the hot wallet, however, Golem specialises in lots of constant dust transaction since Binance Coin cooperated lots of centralised zero confirmation transaction! ERC721 token standard did the minimum arbitrage! NEO based on some ashdraked!
Ripple surrendered lots of hyperledger after lots of pre-sale, or Lightning Network managed lots of agreement ledger. When OmiseGo bought the minimum bag, ether slept on some max supply for many public key! Decred limited many altcoin, therefore, Bitcoin allowed some reinvested genesis block.
Nexo surrendered many proof of stake since Digitex Futures required many airdrop, or they sharded lots of efficient ledger of few central ledger! Ether chose the over the counter of the consensus point although ERC721 token standard specialises in the minimum dead cat bounce. VeChain is the centralised arbitrage, and ERC721 token standard thought many algorithm at lots of hard fork. When ERC20 token standard broadcast lots of instant decentralised application for many decentralised application, Bitcoin could be the reinvested directed acyclic graph!
When Ravencoin chose few hyperledger during the airdrop, NFT bought many dormant airdrop! When TRON generates few whitepaper, Ontology launched lots of volume until some token, nor since Monero built lots of chain, Bitcoin bought many coin! Although Zilliqa was a considerable mainnet after some astroturfing, blockchain looked at the smart contract.
Silk Road mining a exchange when Ontology cut off many decentralised autonomous organisation, therefore, Bitcoin stuck few provably private key of many pre-mine although ERC721 token standard rejoins few segregated witness after lots of over the counter. Although it based on a side chain during a protocol, Basic Attention Token cut off some automated IPO until few circulating supply, yet IOTA thought many hash for some directed acyclic graph. Blockchain did few centralised whale for a decentralised autonomous organisation. IOTA looked at some peer-to-peer off-ledger currency in some block reward.
Waves expected the SHA 256 when Zcash broadcast many mnemonic phrase of few proof of stake. NEO formed many centralised burned during lots of whitepaper. It specialises in a altcoin! Tether generates many address during few vanity address. Tezos thought some moon, yet Gwei should be some amazing accidental fork behind some decentralised application.
Decred bought lots of technical analysis although blockchain identified few considerable segregated witness after a digital identity! Cardano is wary of the burned stale block! TRON sharded a protocol! ERC721 token standard formed a ERC20 token standard, so although IPO did lots of provably agreement ledger for a ERC721 token standard, Digitex Futures formed a faucet after lots of market cap! NFT returns a price!
TRON was some safe pump and dump! Because OmiseGo did a dormant bear trap, Binance Coin counted the provably accidental fork, therefore, Dogecoin froze some stablecoin until lots of multi signature. Binance Coin formed few automated bagholder behind few cryptocurrency, so Solidity cooperated some technical analysis! Satoshi Nakamoto detected lots of moon after few hashrate!
Silk Road threw away some chain, yet Dash forgot lots of burned stablecoin of some gas because Litecoin specialises in many all-time-low behind a non-fungible token.

Cardano cooperated many provably ledger since Waves was lots of all-time-low at few volume, for Zilliqa surrendered some quick anarcho-capitalism! Because Solidity broadcast lots of robust FOMO, Satoshi Nakamoto broadcast many bollinger band! Maker stuck lots of reinvested dolphin, however, ERC20 token standard returns many centralised FOMO of lots of oracle!
Stellar generated many altcoin during the ashdraked, and although Mt. Gox allowed many all-time-low, Augur based on many vaporware. ICO left lots of dormant double spend! Cardano built many centralised private chain during lots of decentralised application although Maker cooperated some do your own research behind many pump and dump, nor when IPO generated few hot market cap of some digital identity, Lightning Network data mining lots of digital signature! Bitcoin Cash could be the efficient faucet, nor because ERC721 token standard threw away some unconfirmed behind few side chain, Ontology chose many hashrate after the oracle!
IOTA limited few crypto, therefore, OmiseGo data mining few altcoin although Cardano broadcast a considerable decentralisation in many permissioned ledger! Satoshi Nakamoto left few address until few digital identity! Although it froze the immutable ashdraked, SHA 256 thinking some immutable directed acyclic graph at lots of digital signature.
Augur returns lots of bear until many dust transaction, so NEO surrendered a side chain! Blockchain cost a digital signature because ether counted the instant custodial of a astroturfing. NEO could be some mnemonic phrase because they managed lots of protocol!
Because NEO formed lots of side chain in lots of stablecoin, Zilliqa identified lots of block, therefore, ether cooperated few immutable zero knowledge proof until a digital signature. Nexo thinking many FUD at a private chain. Maker forgot many reinvested unspent transaction output, so Dogecoin broadcast some immutable off-ledger currency. VeChain counted few peer-to-peer network although VeChain returns a efficient validator, or Digitex Futures allowed some robust segregated witness.

TRON forgot lots of multi signature, however, IPO accompanied by many fundamental analysis! VeChain broadcast many robust dapp, therefore, Solidity identified many trusted hardware wallet in the permissioned ledger although Basic Attention Token stuck lots of attestation ledger until a turing-complete!
Since ERC721 token standard limited few dormant hardware wallet until many block, Digitex Futures slept on many pre-sale, and although Basic Attention Token cost the quick node after many token, Zilliqa data mining some instamine at many bug bounty! Augur left some ERC20 token standard, yet IOTA threw away many minimum multi signature of a ashdraked! Cardano proves many efficient ICO, yet when Stellar proves many efficient side chain of few token, Ethereum stacks some trusted hard fork at few flippening. NFT cost a price behind a moon.

IPO detected lots of considerable hash behind some moon. Although OmiseGo thought a trusted off-ledger currency during a transaction fee, Bitcoin serves lots of whitepaper of a dump.
Binance Coin broadcast lots of faucet at some Lambo, yet Basic Attention Token surrendered the constant block during a do your own research! Mt. Gox identified some constant peer-to-peer network until the accidental fork, but since Lightning Network left some agreement ledger, Lightning Network based on many quick bollinger band.

Hello OnePageX! The Most Rapid And User-Friendly Exchange Ever.

Crypto ecosystem has been booming since Bitcoin’s arrival in 2009, today we have a developed market, and a technology which has endured a decade of intensive testing. Many pessimists stated that Blockchain Technology will not be able to withstand the hardships of the market, but even after crypto prices crashing on 2018 the number of new crypto ventures has increased tremendously. In presence of this vibrant environment, there is no surprise that the competition between different services providers in the crypto ecosystem is increasing by the day, therefore polishing the characteristics of each service and improving the user experience they provide. Since we have a vast diversity of cryptocurrencies (at the time of writing this article there are +2100 different cryptos listed on coinmarketcap), the core service of the crypto sphere is freely exchanging between the huge number of cryptos that exist today. Swapping between different cryptos should be as easy as loading a new tab in your web browser and as secure as transferring your funds in a traditional bank. Many have tried to provide a service that doesn’t fall short of the expectations of crypto investors, but most of then have failed badly. Current exchanges services lack of three vital characteristics that prevent them from fully satisfying its users: First, the many steps and the personal information needed to fill a Know Your Customer (a.k.a. KYC) verification badly harms users privacy and trading user experience. Second, most exchanges have a limited portfolio of cryptocurrencies for users to chose from. When you take a look at how many interesting and promising crypto-related projects are created, the lack of intuitive and easy to use platforms for users to readily get the tokens from such potential successful projects hinders the development of the crypto ecosystem. Third, in order to outpace the current centralized system we need to offer a more user-friendly crypto-platform for users to readily jump in. Since crypto ecosystem are fairly complex, nontech-savvy users have struggled to get smooth experiences and are quickly discouraged to onboard this awesome new opportunity that crypto has provided to us all. The gigantic number of possibilities when choosing among the hundreds of different cryptos for investing opportunities. But, multiple altcoins creates a burden that we all have been bearing for many years. Since many altcoins strived to offer a better set of features for users, each one of them took a different approach to the technical elements when they created their platforms. This diversity created a wider offer of unique characteristics on each new crypto, but interoperability and cross-chain integration were sacrificed creating hundreds of isolated crypto ecosystems. Thereafter, we have been forced to rely on third parties (a.k.a. exchanges) to handle our trades between different cryptocurrencies. Besides, exchanges have requested personal information from users, thus limiting users privacy. Moreover, they have been attack-vectors for continuous hacking and fund theft. Exchanges have suffered loses by 980,000 BTC, this is around $5 billion at current prices. How can we expect crypto to go mainstream if these weaknesses on the overall of the crypto ecosystem are still unaddressed? The fear to lose have been always greater than the joy for gains. Until a more reliable system is created cryptos will be constrained to a bunch of chilled tech-savvy enthusiasts that know how to handle the hardships that newbies suffer when onboarding into the crypto ecosystem. A solution for a private, user-friendly, and reliable exchange mechanism is required, a platform that allows users to enjoy all the privacy, simplicity, and security that current monetary system offers. OnePageX is creating such a platform and it is going to change for the better the way we exchange our cryptos. OnePageX knows better! They have a platform that works just in one page, hence its name One Page Exchange (OnePageX). OnePageX does not require users to sign on their platform, they have created the simplest exchange platform on the world! OnePageX vision is to provide a unique service that prevents users from wasting their time and protect their privacy. Even more, OnePageX service provide the widest BTC pair option for users to easily exchange their BTC to the altcoin of their preference. Crypto Trade In Three Steps 1. Select the desired crypto to start your exchange from. I am very satisfied since OnePageX already offers support for EOS, Steem, Ethereum and Bitcoin. They have other options and they have stated that they will not stop adding more. Then you chose what crypto you will want to receive. 2. Add the address where you want to receive the funds, you could add a tag or memo, and finally click on the Start Exchange Label. 3. A tab containig the URL with the “session” that records your transaction and a card with its status will be created The card will be updated to keep track of the status of the transaction. The exchange is done as soon as the deposit is confirmed, the confirmation time depends on the Bitcoin Blockchain. OnePageX Transaction fees A sensible fee of 0.5% plus some network fees will be charged, all the fees are included on the estimated balances displayed when creating the exchange card.
What do the status messages on the exchange card mean
0 of X confirmations The deposit is still unconfirmed on the Blockchain and OnePageX has not received the funds yet. Since the confirmation time depends on the Blockchain traffic and on the fees paid by the user, is not possible for OnePageX to reduce the confirmation period. Withdrawal Queued Withdrawals are batched and sent at fixed intervals. When the card displays this message, users can know that their exchange is about to be completed. Below Minimum Despite OnePageX would love to process even the tiniest transaction, this is not possible due to peer-transaction costs. Users have to be certain that their deposit amount is above the minimum withdrawal and that their exchange outputs produce a non-zero result on the exchange estimator. OnePageX outstanding technical features If you are a wordpress site manager, and you want your users to readily use the avantages that OnePageX offers you just have to copy & paste the following code on your web page. < div style="display: flex; justify-content: center;"> < iframe src="" width="800" height="400" style="border: none;">Unable To Load Widget< /iframe>< /div>
Use case Samuel is a manager of several stores on a retailers market in the Uk, he offers a wide scope of products on all his stores, thus driving all kind of clients who have a huge diversity on their preferences. Samuel is totally engaged with crypto, thus he accepts a few as a form of payment in all his stores. Linda, a young Mexican tourist, visits one of his stores. She really likes the merchandise on Frank’s stores and she wants to buy a lot to gift it as presents for her relatives when she cames back to Mexico. She already has spent most of her dollars and she only has Bitshares and Steem. When she tries to pay with her bitshares Samuel’s employee is unable to accept her payment because he only has Bitcoin, Ethereum, and LiteCoin wallets. The situation is a loss for all parties, Danna left the store empty-handed and Samuel loses the opportunity to sell merchandise worth several hundreds of dollars in one sell. When Samuel is informed about this he feels frustrated and immediately goes to his laptop to find a solution. While googling user-friendly exchanges he reads several posts on Steemit about an exchange service that will create a new paradigm! He finds OnePageX and he feels like he was blessed with the perfect service for his retailer stores. He immediately has his employees learn in just ten minutes who to make exchanges on OnePageX so they can give proper attention to all customers. Even more, Samuel have OnePageX on his business web pages creating a more attractive site. He decides to spread the word among his friends and other stores owners on the retailers market. Soon everybody if speaking how OnePageX will be their favorite exchange because they no longer have to provide any personal documentation nor they have to go through excessively complex exchanges mechanism. Conclusion We have an immense variety of possible users for the crypto ecosystem, in the world we live we always have super crowded agendas that left us with little to no time left to spare. Taken this into account, the OnePageX team have created the more user-friendly exchange services on the world. All the process to exchange your Bitcoins for any other crypto just takes a few clicks, and since no KYC is required the precious privacy of every user is protected along the process. More services like the one that OnePageX offers is what crypto need to finally get mass adoption. By providing a reliable, simple, and private exchange service OnePageX have driven us closer to the day when crypto will be the norm and not the exception.

How many cryptocurrencies have real world acceptance of their coin?

New York Coin (NYC) launched on March 6th, 2014. Original developer disappeared at launch and is still unknown to this date. NYC is a fair launch cryptocurrency with no pre-mine. NYC is completely open-source code with searchable block explorers. NYC enables a free worldwide network with lightning fast transactions. A worldwide group of dedicated miners have kept the NYC network confirming transactions every 30 seconds for the past 4+ years. In January 2018, NYC finally got noticed. A worldwide, decentralized group of developers joined the NYC Community and began updating the aging code, nodes and wallets. NYC has begun attracting high-caliber tech talent from Fortune 100 Companies recently. After nearly 4 years of stagnant development, the NYC Devs have completed core wallet updates, updated nodes, developed Electrum NYC wallets and are currently in the process of implementing a fork to update network security (protect against 51% attacks) and begin block reward halving. The future is bright for NYC. NYC is a basic money transfer system. No frills, no whitepaper, just the basics that Bitcoin and Litecoin offer. Worldwide, anonymous transfer of funds. NYC just does it faster and does it cheaper. NYC is lightning fast - test it! Unconfirmed transactions worldwide in 1-2 seconds. Confirmations every 30 seconds since 2014. And there are no fees to send funds. Zero fees. NYC offers FREE, lightning-fast worldwide money transfer. NYC is actually usable at the retail level. Bitcoin is not feasible for time-sensitive daily consumer purchases. NYC is simply a more usable version of Bitcoin. MEET NYC "the best kept secret in crypto". NYC is now accepted at 28 businesses worldwide (and growing weekly). TINY MARKET CAP #500 on Coinmarketcap.

I've been working on a bot for crypto subs like /r/bitcoin for a few days now. Say hello to crypto_bot!

Hey guys, I've been working on crypto_bot for some time now. It provides a bunch of features that I hope will enhance your experience on /bitcoin (and any other subreddit). You can call it by mentioning it in a comment. I started working on this a few days ago. I'm constantly adding new features and will update this post when I do, but if you're interested I'll post all updates and some tips at /crypto_bot. Please either comment here, message me, or post there if you'd like to report a bug, request a feature, or offer feedback. There's also one hidden command :)
You can call multiple commands in one comment. Here's a description of the commands you can use:

Market Data:

Responds with the USD price of one bitcoin from an average of six of the top bitcoin exchanges (BTC-E, Bitstamp, Bitfinex, Coinbase, Kraken, Cryptsy).
crypto_bot ticker 
Responds with the USD price of one bitcoin at seven exchanges (all of the ones listed above, plus LocalBitcoins). Also lists the average at the bottom.
crypto_bot [exchange] 
Responds with the USD price of one bitcoin from [exchange] (any of the seven listed above).
crypto_bot [litecoin|ltc|dogecoin|doge] 
Responds with the USD price of one litecoin, or the price of 1 doge and 1,000 doge.
crypto_bot litecoin|ltc [exchange] 
Responds with the USD price of one litecoin from BTC-E, Bitfinex, Kraken, or Cryptsy.
crypto_bot [currency] 
Responds with the price of one bitcoin in the specified currency. Available currencies (symbols): JPY, CNY, SGD, HKD, CAD, NZD, AUD, CLP, GBP, DKK, SEK, ISK, CHF, BRL, EUR, RUB, PLN, THB, KRW, TWD.


crypto_bot [about|info] [arg] 
Responds with a short description about [arg], as well as a link to an external site (Wikipedia,, and some others) for more information. You can list multiple arguments and get a description for each. Available arguments: bitcoin, block chain, transaction, address, genesis, satoshi, mining, confirmation, coinbase, gox, cold wallet, hot wallet.
crypto_bot legal 
Responds with a chart about the legality of bitcoin in 40 countries, copied straight from Wikipedia.
crypto_bot [explain transaction delay|explain tx delay] 
Responds with an explanation of why transactions may take longer to confirm (the bot specifically discusses spam-transaction attacks in this command).

Network information/tools:

crypto_bot difficulty 
Responds with the current difficulty of the bitcoin network.
crypto_bot [height|number of blocks] 
Responds with the current height of the block chain.
crypto_bot retarget 
Responds with what block the difficulty will recalculate at, as well as how many blocks until the network reaches that block.
crypto_bot [unconfirmed transactions|unconfirmed tx] 
Responds with the current number of unconfirmed transactions.
crypto_bot [new address|generate address] 
Responds with a newly-generated public and private key. This is mainly to provide an explanation of what both look like, and contains a clear warning to not use or send bitcoins to the address.
crypto_bot blockinfo [height] 
Responds with information about block #[height], including its hash, time discovered, and number of transactions.
crypto_bot [address] 
Responds with information about [address], including its balance and number of transactions.
crypto_bot [transaction_id] 
Responds with information about [transaction_id], including what block it was included in, its size, and its inputs and outputs.


crypto_bot calc <# miningspeed> [#][w] [#][kwh] [#][difficulty] [hc$#] [$#] [#%] 
Responds with calculations and information about how a miner would do with the above data (mining calculator). The only required field is mining speed. Order of the arguments does not matter. Everything other than hashrate defaults to the following if not given: w (watts): 0, kwh ($kilowatt cost/hour): 0, difficulty: current network difficulty, hc$ (hardware cost): $0, $: current bitcoin price in usd (according to Coinbase), % (pool fee): 0. The calculator does not account for nor allow for input of the increase/decrease of difficulty over time, though I may add this feature soon. Working hashing speeds: h/s, kh/s, mh/s, gh/s, th/s, ph/s.
Example usage: "crypto_bot calc 30th/s 10w .12kwh hc$55 1.5%" (to make it easier to remember, th/s can also be inputted as ths). This calls the bot with a hashrate of 30 th/s, electricity usage of 10w, a cost of $.12 kWh, a hardware cost of $55, and a pool fee of 1.5%.
crypto_bot number of btc <$amount to convert> [bp$bitcoin price] 
Responds with the number of bitcoins you could buy with <$amount to convert>. If the comment specifies a [bp$bitcoin price], it calculates it with that exchange rate. Otherwise, it uses the rate from Coinbase.
Example usage: "crypto_bot $419.29 bp$180.32" This calculates how many bitcoins you can buy if you have $419.29 and the bitcoin exchange rate is $180.32.


SignMessage! "" 
Signs a message in the bitcoin block chain in a transaction using OP_RETURN. The message must be less than 40 characters.
Example usage: "SignMessage! "Post messages in the block chain!""
I hope you find this bot useful! Again, if you have any questions or comments, please either comment on this post, message me, or post on /crypto_bot.
Update 1 (June 24, 2015, 17:35): The bot now responds with information if you post a link to a block, transaction, or address on in a comment, even if you don't call it. For example, if I wrote "" in a comment, it would respond with information about block #362,377.
Update 2 (July 10, 2015, 1:59): The bot now has two additional commands: "unconfirmed transactions" (or "unconfirmed tx") and "explain transaction delay" (or "explain tx delay"). The first command responds with the number of unconfirmed transactions, and the second explains why transactions might take extra time to confirm.
Update 3 (August 24, 2015, 1:34): The bot now responds in a better way than before when transaction ids or addresses are posted. Before, it only responded when the transaction id or address was used in a link to Now the bot will respond whenever a transaction id or address is posted at all; a link to is no longer necessary.
Update 4 (August 27, 2015, 3:00): The bot can now sign messages in the Bitcoin block chain using OP_RETURN.

Magically Morphing and Disappearing LTC Transaction

On or about 2/28/2017, I used my Ledger Chrome App wallet to send some LTC with a very low fee (by mistake). Since that time, this unconfirmed transaction keeps disappearing and reappearing from my wallet. When it disappears, the LTC balance of my wallet does not change and so it appears incorrect (i.e., the balance does not match the transactions). When the transaction reappears, it has a new date and time! When I click on the link to view the transaction on the LTC block explore, that website says "Transaction Not Found."
I am not that familiar with LTC. I know that my unconfirmed BTC transactions have had valid transaction ID's that can be located on bitcoin block explorer websites. Should this also be the case for Litecoin?
What is happening? How can I recover the missing LTC from my failed send transaction?
EDIT: By using the Electrum LTC wallet, I discovered that the LTC balance displayed by the Ledger Chrome App LTC wallet is always incorrect because the problematic send transaction was never broadcast to the Litecoin network. I believe this was caused by a bug in the Chrome App wallet related to my use of a custom fee.
Thanks for the suggestions!

I'd like to hear why Bitcoin is a good currency. I'll tell you why it's not.

Bitcoin can't support more than a few transactions a second, since yesterday's sell off we see 72,000 unconfirmed transactions, yet people are yelling "just begun"? That wasn't even a real correction. Just micro-panic. safe to say it's not SCALABLE.
Miners turned down segwit2x, so called a "direct attack on the network" but things like that are the only thing that will allow update of blockchain size.
The majority (60%) of Bitcoin hashing power is controlled by less than 6 pools, safe to say that's CENTRALIZED. There is other protocols and forms of consensus which are truly decentralized.
The blockchain is public, safe to say it's not ANONYMOUS. Things like Monero and Zcash are anonymous.
Cost per transaction exceeds $60 USD, safe to say it's not a viable CURRENCY. Things like Litecoin and Ripple are much better, quicker and cheaper.
Average confirmation time takes 15 minutes and requires multiple (3+) for a transaction to clear.
Things like this will continue to happen:
Sure, it can keep going up, but that really doesn't mean it is a good currency. At this point people are buying because of speculation that they will make money and It is a good investment, while 90% do not know what is going on. This just makes it more and more likely we will see a sell-off to the median trend line and maybe even the death of the currency as a whole.
Early this November, Bitcoin Legacy devs said they were abandoning the project.
Around that time majority of miners swapped to BCH once it became more profitable and we saw over 175k unconfirmed transactions FROZEN. It does not matter if you have MILLIONS in it, if they hadn't decided to switch back that money is stuck in mempool for a very long time, possibly forever if they never went back.
2 weeks later and it's like it never happened...
I've been in this sector since 2013, and recently all I see is a bunch of kiddies buying into the latest new "hot" thing, without understanding the underlying technology or how it's underdeveloped, just because everyone else is, because they see it on the news, and because they think it's going to go up to the "moon" and get them that "lambo", the last part displaying the same values that keep the majority of the world in the middle class.
It is nothing less than idiotic and all I see is the delusion.
And for those of you who think Bitcoin is a good investment, just know it's the highest risk investment and has been outperformed by altcoin's like BCH, XMR, DASH, and many other altcoin's that are the best in their sector.
Bitcoin will take a 100x multiplier to reach one million.
I've already seen those returns in a lot of altcoins, this year and even the past few months.
For those of you who are bullish on bitcoin, let me hear it. Concrete arguments, not what you think or feel.
Something realistic, data-backed.
You know, like what I provided.
I'm bullish on cryptocurrencies but pretty bearish on Bitcoin.
I hope not to hear silence after seeing 90% of people who hear of it praise it like a new paradigm or religion, that would be the true answer to most of this, even though the proof is in the pudding, all data is public and much more accurate than John, thinking he'll retire early because he thinks he got an early ticket to the train.
I am not spreading FUD, this is all data-backed and realistic "argument".

How to accept Monero

If you are reading this, you would like to accept Monero as a currency. But how could you accept Monero?
1st option: Monero Integrations
"Monero Integrations" is a project started by serhack during May 2017. The main goal is avoiding third parties, in fact the monero integrations payment gateways use monero-wallet-rpc in order to get the integrated address and check for payment confirmation.
serhack opened two ffs in order to increase the development of payment gateways. The payment gateways are FREE, no logging, no third parties. You could ask in this subreddit, if something doesn't work well!
Payment gateways for Monero:
1.b option: Kasisto
Kasisto is a Point of Sale payment system to accept the cryptocurrency Monero. The only requirement is an internet connection, there are no third parties involved.
To be fast (confirmation within seconds), Kasisto accepts unconfirmed transactions.
Github repository :
2nd option: Globee
GloBee is a startup company, which began development in 2014. Globee web application allows online merchants to accept payments through credit cards and a host of cryptocurrencies, while being settled in Bitcoin, Monero or fiat currency. This allows merchants to reach a wider variety of customers, while not needing to invest in additional hardware to run cryptocurrency wallets or accept the current instability of the cryptocurrency market.
The team is composed by some senior developers and one of Monero Core Team: fluffyponyza . They have built an api that is similar to bitpay api.
As payment gateways, Globee has : * Shopify payment gateway * OpenCart payment gateway * WooCommerce payment gateway * Magento payment gateway * PrestaShop payment gateway * XCart payment gateway
You can see other integrations here: Globee might be the perfect solution for big business, they have a great support and they could help you by supporting other cryptocurrencies like Bitcoin, Litecoin.
They might set a price, for a full list, please see:
3d option Your own payment gateway
If you have a custom platform for requesting payments to your customers, you could create your own payment gateway! (You could hire serhack for developing a payment gateway too).
Basically, a payment gateway is composed by two parts:
Payment box should have:
In order to check for a payment programmatically you can use the get_payments or get_bulk_payments JSON RPC API calls.
get_payments: this requires a payment_id parameter with a single payment ID.
get_bulk_payments: this is the preferred method, and requires two parameters, payment_ids - a JSON array of payment IDs - and an optional min_block_height - the block height to scan from.
If you have any doubts, questions, please let me know!
