Bitcoin Hashrate Records New All-Time High Amid Halving And BTC Bullish Momentum
With The Third Bitcoin Halving Already Here, Bitcoin Bulls Are Showing No Signs Of Support For The World’s Leading Cryptocurrency While the crypto world was frantic about Bitcoin’s third halving event, which occurred on May 12, it came with a bullish sentiment among traders and holders. However, the halving produced 5%-8% price swings in both directions prior to the halving. The market didn’t seem to respond to the much-anticipated halving. The weekend saw $1,3 billion in liquidations, which put pressure on Bitcoin bulls. Shortly after Bitcoin’s reward cut, Bitcoin’s price peaked, before correcting itself to currently trading at $8,745.98 Meanwhile, the Bitcoin mining industry seems to be going all-in on validating blocks, as the computing power on Bitcoin’s network, or hashrate, increased to a new all-time high. The 140 terra hash-per-second (TH/s) all-time high surpassed the recent 135 TH/s all-time high of March 2020, meaning that miners deployed all their recourses to celebrate the halving event. Source: Coinwarz The crypto community welcomed the halving, as TIE published data, showing the word “halving” being present in over 2,900 tweets. Reddit also showed signs of buzzing in the moments prior to the halving and shortly after it. Joshua Frank, TIE’s founder commented on the data, stating that “Bitcoin became a hot topic in the past 30 days, with a 72-percent conversation surge, and with peaks in search terms of Bitcoin and halving crypto related terms in Twitter. Bitcoin also surpassed 50,000 daily tweets, which is a new six-month high.” Source: Twitter “In the 30-day window prior to the halving, the word “halving” appears to be dominant in the conversations, regarding Bitcoin,” Frank added. Google searches for “bitcoin halving also increased four times, as opposed to the 2016 halving event. However, most crypto enthusiasts believed Bitcoin would record double, or even triple-digit price increase, due to the halving. The short rally proved them wrong, but many consider the real price surge to start in the following 18 to 24 months. Historically, Bitcoin showed an initial decrease in value before skyrocketing in both price and trading volumes. The halving event drove an increase in daily trading volumes in the month before the reward cut. However, trading volumes have increased 50 times since the last halving in 2016. Spot market volumes received a boost from a peak of $1,5 billion in June 2016, and it was close to $30 billion in April 2020. Nevertheless, market players are still stagnant about making strong predictions about Bitcoin’s future price, as this time it would take longer for the market to gain from the bullish momentum the halving created.
I'm not at all experienced with crypto or mining, but I am a software dev by profession so I have some technical ability. I have an idea for a gift for someone who is a long-time bitcoin user, but I'm not sure how to do it or if it's possible. I'd like to buy time or "credits" or something on a GPU rig that they can use at their leisure. It seems that, based on sites like this (https://www.coinwarz.com/cryptocurrency) that one could use GPU hours to "time" their mining and choose which currency to mine, with a goal of maximizing conversion back to bitcoin? Does this even make any sense, and does anyone know how I could go about doing it if so? Thanks in advance, happy holidays!
A short Background 2008 was the worst financial crisis the world had experience since the great depression. The efforts of banks worldwide were not enough to prevent its occurrence. Shortly after, someone by the name of Satoshi Nakamoto offered an alternative solution. A digital currency that removes the need for a central bank. His proposal written in the Bitcoin white paper, is summarized below:
A secure, decentralized network.
A system with economic properties.
No need for banks or rule makers.
Instant transactions without a need of a third party or government approval.
Bringing financial services to the unbanked 2.5 billion people.
Total financial freedom. No one can freeze your accounts.
Low transaction costs. No ridiculously high transaction fees.
A currency with finite amount where no one can print money whenever they want.
Bitcoin In 2009, when Satoshi Nakamoto launched Bitcoin, the network consisted of computers (in crypto terms, these are called Nodes) to approve transactions, movements of data along the chain. This allows for everyone willing to become a participant, creating a decentralized global network. Allowing for a decentralized currency, free of the control of politicians, or institutions. The rules can only be changed if 51% of the network agrees on it. This way the network is completely democratized and resistant to hacking attacks. Unlike today’s financial institutions, no one can freeze your account or prevent you sending money. You are the only person who truly holds your wealth. It is an open source project. Anyone can see the code and offer or discuss changes with the community. On the other hand, anyone participating to the network with computational power gets incentives or pay, with a fractional amount of BTC. Blockchain The core of a secure decentralized network like Bitcoin, lies the Blockchain technology. To put it simply, the blockchain is like a series of Lego, connected to each other by linking information, called transactions. These transactions contain the following data sender, receiver and the unique signature of the sender. The data will be converted into “hash” before being saved into a block. The bitcoin hash is generated using a set of cryptographic functions called sha256. This way the information is encrypted, is compressed and saved in the block. Additionally, each block in the chain, contains the information from the block before it. This ensures that if someone tries to maliciously modify information in a block, all the block following this attempt will be changed, making it easier to spot. Each block includes the information from the previous block. If someone wants to maliciously change the information in one block that change the complete result of all following blocks. In this type of network there is only one blockchain, and all the information is kept in a public ledger which is shared amongst all the participating networks. For the blockchain to be valid, more than 50% of the participants (nodes and their computational power) must agree with it. Bitcoin Today (2018) Until today many, many, events have happened. The network has grown massively. The underlying code is improved in many ways. There are more and more developers and investors that have entered the cryptocurrency space. Currently there are proposed changes being developed to the Bitcoin network that will make bitcoin rival the centralized networks of today (Visa, Mastercard), while significantly lowering the cost of these transaction. Many alternative cryptocurrencies have been created along the way, improving some of the aspects of the bitcoin and focusing on certain applications, in the crypto-space, we call them altcoins. WHY VERGE The way that Bitcoin function, has severe flaws with regards to privacy:
Public Ledger: The transaction information is public, meaning, that transactions can be linked to a person.
IP Leakage: A persistent and motivated attacker will be able to associate your IP address with your bitcoin transaction.
Due to the above reasons, it was clear that there would be a need for a privacy coin. Different coins were then created that had this problem in mind. They were ‘too private’ in the sense that they completely by-passed the public ledger. The public ledger allows merchant to provide proof of transactions, which is important for bookkeeping. Enter Verge Currency, formerly Dogecoindark; which offers transaction on the ledger, both public and private. Allowing the user to choose if the transactions are public or private. VERGE CURRENCY 2014 saw the birth of Dogecoin Dark; in 2016, it was rebranded to Verge Currency. Verge improves upon the original Bitcoin blockchain and aims to fulfill its initial purpose of providing individuals and businesses with a fast, efficient and decentralized way of making direct transactions while maintaining your privacy. What is the Verge Currency Mission? Verge Currency aims to empower people around the globe using blockchain in everyday life and makes it possible for people to engage in transactions quickly, efficiently and privately. With Verge, business and individuals now have flexible options for sending and receiving payments. Verge Currency also offer helpful integrations and tools that enable them to handle large scale transactions between merchants and small-scale private payments. Is Verge Currency a private company and how is it funded? Following in the spirit of Bitcoin, Verge is an open-source software, and a community. It is not a company, never had an ICO. The development is entirely funded by the community and the developers. Currently Verge is looking into setting up an official Verge merchandise store, and an Official Verge mining pool, for multiple algorithms. Tech General technical capabilities of XVG blockchain:
PoW (Proof of Work)
Scrypt, X17, Lyra2rev2, myr-groestl and blake2s

Community Verge is a community-driven project. The community is the pillar of Verge, from the past to the future, the community built Verge. The community or Vergefam connects everyone from around the world, regardless of cultural background. The common vision is to provide everyone access to financial freedom, and the choice of privacy while transacting. Below you can find the Verge Telegram communities from around the world;
Mass Adoption Low fees, quick transactions, high volume in circulation, multiplatform support, Wraith protocol are the ingredients that make Verge perfectly positioned for mass adoption. Transact on the public ledger for everyday purchases or stay private if you wish so. Getting Started You can find the matching instructions as below:
Antes de qualquer coisa gostaria de fazer um ‘disclaimer’ sobre esse post:
Não estou aqui para fazer aquele marketing “Olhe como em apenas 5 passos você pode ficar muito rico!!”. Eu sou extremamente novo nesse mercado de Criptomoedas e aprendi tanta coisa nova e legal e gostaria de compartilhar meu conhecimento, tirar duvidas e quem sabe trazer novas pessoas nesse novo mundo.
Nesses últimos tempos vários posts sobre Bitcoin e Altcoins estão aparecendo aqui no /Brasil e muita gente discute sobre o assunto. Alguns extremamente céticos, uns curiosos e outros que já conhecem um pouquinho do assunto. Eu tentei dar um help pro pessoal que fez perguntas nos outros posts e alguns se juntaram ao grupo que organizei sobre Criptomoedas no Discord.
Não quero trazer também o “invista até não poder mais”. Esse mercado de criptomoedas é extremamente volátil e você pode sim perder dinheiro com isso. Nunca invista o que não pode perder.
Quero iniciar comentando sobre algo que muitos céticos usam:
“Bitcoin é uma bolha, ela vai estourar e você vai perder tudo.”
A ideia central de Criptomoedas é ser um sistema descentralizado de qualquer banco, empresa e governo, ser seguro, open-source, totalmente criptografado, que é apoiado pela matemática implementada. Toda a história da moeda deve ser aberta ao público e você pode ver toda e qualquer transação feita na rede. Essas transações precisam ser processadas por máquinas que confirmam que essa transação não é um double-spending ou alguém querendo criar moedas “out of thin air”. Se alguém quiser hackear o sistema ele vai precisar quebrar toda a Blockchain da moeda (explicação mais abaixo).
Blockchain (cadeia de blocos) é todo o registro de tudo que aconteceu com a criptomoeda. Cada novo bloco é ligado ao ultimo bloco existente. Nenhum dado subsequente pode ser alterado sem que todos os outros blocos sejam alterados. Fazendo assim a criptomoeda em questão super segura. Blockchain é estudada para aplicações de gerenciamento de identidade, registro médico, prova de documentos, etc.
Você pode fazer uma transferência pequena de alguns trocados até com centenas de milhares Reais para qualquer lugar do mundo. Imagine você aqui no Brasil tem um parente lá na Coréia do Sul. Você quer mandar R$3000,00 para o parente. Para isso você precisa ir até o seu banco, solicitar uma transferência de alto valor, pagar todas as taxas do banco, do seu governo, talvez até do governo do país que será enviado, esperar até a data estipulada para o dinheiro chegar ao seu parente (a partir do dia do envio+2). Faça a pesquisa, você pode pagar muito alto por isso.
Agora leve em consideração o Bitcoin. Mesmo com uma taxa alta nesses últimos tempos (da ultima vez eu paguei R$12,00), imagine você mandar esses mesmos R$3000,00. Só que a transação é feita em até 60 minutos. Você manda a ordem de transferência da sua carteira até a carteira do seu parente, essa transferência de Bitcoin é registrada, então processada pelos mineradores e depois de um tempo o Bitcoin é validado na carteira do seu parente. Depois disso ele pode já usar os Bitcoin no mesmo dia ou ir até um caixa eletrônico de Bitcoin e sacar em dinheiro ou até trocar por outras moedas ou por dinheiro em Exchanges.
Fora Bitcoin, nós temos centenas de outras criptomoedas. Várias são muito interessantes, como: Ethereum, Litecoin, Bitcoin Cash, Vertcoin. Outras são simplesmente enganações usadas para roubar dinheiro de quem investe nas criptomoedas. Infelizmente existem coisas ruins como essa em qualquer lugar do mundo. Sugiro também uma pesquisa sobre cada criptomoeda. Coinmarketcap é um site legal para você iniciar sua pesquisa nas moedas de maior valor, volume, tecnologia, etc.
A mineração consiste em usar o recurso de processamento do seu computador para procurar e resolver blocos. Quando isso acontece uma recompensa é distribuída para todos os mineradores envolvidos na mineração. Você pode minerar sozinho (o que hoje é impossível para alguém normal) ou pode entrar em uma Mining Pool.
Recentemente comecei a minerar uma criptomoeda chamada Vertcoin. Não é necessário muito conhecimento em como funciona a mineração. Basta ter um computador com placa de vídeo legal (a partir de uma gtx 1060 é legal), baixar um programa chamado One-Click Miner (OCM), arranjar uma carteira da moeda (interessante a Electrum Vertcoin Wallet), apontar seu minerador para aquela carteira, selecionar uma Pool de mineração e clicar Start.
Na mineração de Vertcoin você usa o poder de processamento da sua GPU para procurar blocos na rede junto com vários outros mineradores. Quando um bloco é encontrado você é recompensado pelo tempo que você esta minerando. Quanto mais tempo estiver minerando, melhor. Mas até um limite claro.
Não vou dizer que vale a pena você minerar porque existem muitas variáveis para isso. Para mim esta valendo a pena. Com uma GTX 1080 consigo pagar o gasto extra de conta de luz e lucrar Vertcoins. Recomendo fazer o calculo e ver se vale a pena.
A ideia central que estou levando para minerar Vertcoin é que devido a sua história, seus desenvolvedores, resistência à ASIC (Application Specific Integrated Circuits) e sua transparência com a comunidade ela será adotada pelo mercado. Seu valor subiu de US$0,04 em Janeiro de 2017 para hoje no preço de US$5,4. Outra coisa legal é que o Vertcoin usa algoritmo criado por brasileiros, chamada Lyra2!
Se você, leitor, tiver interesse em minerar ou discutir mais sobre moedas e conhecer mais, eu vou sugerir entrar no Discord que criei exatamente para isso: https://discord.gg/aWfV2Q5. Somos um grupo pequeno, mas o pessoal lá é super amigável e me trouxeram muito conhecimento novo. Temos desde iniciantes até alguns veteranos no assunto. Temos uma Pool de mineração de Vertcoin (Veja aqui) também se alguém se interessar.
Esse mundo de Cryptocurrencies é muito novo, estranho, inovador e interessante. Aprendi muita coisa e nem estou a tanto tempo assim aprendendo. Tenho comprado, vendido, minerado e guardado várias moedas diferentes. Tenho lucrado uma grana interessante que não teria vindo caso continuasse igual meus amigos que dizem não ter dinheiro pra investir nisso, mas saem todo final de semana com amigos/namorada e gastam 50, 100, 200 reais. Deixasse de sair 1 fim de semana por mês e compra uma moeda “segura” como Litecoin ou Ethereum. Da um lucro legal em uns 10 anos caso for atento, trocar por Real quando necessário ou mudar pra outra moeda.
Tem muita coisa que ainda quero falar, mas não quero deixar esse texto mais extenso do que esta. Por isso, peço a você que está lendo para deixar seus comentários, a favor ou contra, que vou tentar responder, aprender coisas novas, tirar dúvidas, fazer perguntas também e ter discussões saudáveis.
Hashflare +-zero if 10% difficulty increase every 14 days in average! (we have even higher now!)
Simple calculation. 365 days mining (contract) means 26 difficulty changes (every 14 days). Imagine it's always 10% increase... safe and exactly 10%. That means, that we increase our difficulty from "1873105475221" to "22323905475221". To do it simple: we increase from 1873 to 22323. This is an increase of 1191%. (26 times 10% increase in a row). Taking now every difficulty value after 14 days for the whole 365 days and then taking the average from all of it we get (simplified) 8401. According to this website, a 17 TH/s contract with ~17% pool fees (hashflare) and a safe block reward of 12.5 all the time, a static btc price of 17.500$ and the price for 17TH/s-contract (OLD PRICES!) it means that you do a +-zero with this contract, if the difficulty would be like 10% all the time. https://www.coinwarz.com/calculators/bitcoin-mining-calculato?h=17000.00&p=0.00&pc=0.00&pf=17.00&d=8401205475221.60000000&r=12.50000000&er=17500.00000000&hc=2695.00 tl;dr: lets hope that difficulty wont increase 1x% every 14 days from now. lets hope btc value wont drop back to 10.000USD or even less. tl;dr2: If difficulty is higher than hoped for, but BTC increases to 30.000USD you obviously did some money with your hashflare contract. But if you just buy the coin from a marketplace today for 17.500 USD you would have done MORE money with just keeping it in your wallet than cloud mining with hashflare. tl;dr3: dont trust those youtubers, they just do tons of money with affiliate programs and not with mining. KEEP THIS IN MIND PLX, it's looking like free money without working for it, but think about your dad's wise words: you will get nothing free in life! sry for bad english.
Why Verge Needs DigiShield NOW! And Why DigiByte Is SAFE!
Hello everyone, I’m back! Someone asked a question recently on what exactly happened to XVG – Verge and if this could be a problem for DGB – DigiByte - Here: DigiByte vs Verge It was a great question and there have been people stating that this cannot be a problem for us because of DigiShield etc… with not much explanation after that. I was curious and did a bit more investigating to figure out what happened and why exactly it is that we are safe. So take a read.
Some Information on Verge
Verge was founded in 2014 with code based on DogeCoin, it was initially named DogeCoinDark, it later was renamed Verge XVG in 2016. Verge has 5 mining algorithms as does DigiByte. Those being:
However, unlike DigiByte those algorithms do not run side by side. On Verge one block can only be mined by a single algorithm at any time. This means that each algorithm takes turns mining the chain.
Prior to the latest fork there was not a single line of code that forced any algo rotation. They all run in parallel but of course in the end only one block can be accepted at given height which is obvious. After the fork algo rotation is forced so only 6 blocks with the same algo out of any 10 blocks can be accepted. - srgn_
Mining Verge and The Exploit
What happened then was not a 51% attack per say, but the attacker did end up mining 99% of all new blocks so in fact he did have power of over 51% of the chain. The way that Verge is mined allowed for a timestamp exploit. Every block that is mined is dependent on the previous blocks for determining the algorithm to be used (this is part of the exploit). Also, their mining difficulty is adjusted every block (which last 30 seconds also part of the exploit). Algorithms are not picked but in fact as stated previously compete with one another. As for difficulty:
Difficulty is calculated by a version of DGW which is based on timestamps of last 12 blocks mined by the same algo. - srgn_
This kind of bug is very serious and at the foundation of Verge’s codebase. In fact, in order to fix it a fork is needed, either hard fork or soft fork! What happened was that the hacker managed to change the time stamps on his blocks. He introduced a pair of false blocks. One which showed that the scrypt mining algorithm had been previously used, about 26 mins before, and then a second block which was mined with scrypt. The chain is set up so that it goes through the 5 different algorithms. So, the first false block shows the chain that the scrypt algorithm had been used in the recent past. This tricks it into thinking that the next algorithm to be used is scrypt. In this way, he was essentially able to mine 99% of all blocks.
Pairs of blocks are used to lower the difficulty but they need to be mined in certain order so they can pass the check of median timestamp of last 11 blocks which is performed in CBlock::AcceptBlock(). There is no tricking anything into thinking that the next algo should be x because there is no algo picking. They all just run and mine blocks constantly. There is only lowering the difficulty, passing the checks so the chain is valid and accepting this chain over chains mined by other algos. - segn_
Here is a snippet of code for what the time stamps on the blocks would look like:
SetBestChain: new best=00000000049c2d3329a3 height=2009406 trust=2009407 date=04/04/18 13:50:09 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=000000000a307b54dfcf height=2009407 trust=2009408 date=04/04/18 12:16:51 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=00000000196f03f5727e height=2009408 trust=2009409 date=04/04/18 13:50:10 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=0000000010b42973b6ec height=2009409 trust=2009410 date=04/04/18 12:16:52 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=000000000e0655294c73 height=2009410 trust=2009411 date=04/04/18 12:16:53 ProcessBlock: ACCEPTED (scrypt)
Here’s the first falsified block that was introduced into the XVG chain – Verge-Blockchain.info As you can see there is the first fake block with a time stamp of 13:50:09 for example and the next is set to 12:15:51, the following two blocks are also a fraudulent pair and note that the next block is set to 12:16:52. So essentially, he was able to mine whole blocks - 1 second per block!
This exploit was brought to public attention by ocminer on the bitcointalk forums. It seems the person was a mining pool administrator and noticed the problem after miners on the pool started to complain about a potential bug. What happened next was that Verge developers pushed out a “fix” but in fact did not really fix the issue. What they did was simply diminish the time frame in which the blocks can be mined. The attack still was exploitable and the attacker even went on to try it again! “The background is that the "fix" promoted by the devs simply won't fix the problem. It will just make the timeframe smaller in which the blocks can be mined / spoofed and the attack will still work, just be a bit slower.” - ocminer Ocminer then cited DigiShield as a real fix to the issue! Stating that the fix should also stipulate that a single algo can only be used X amount of times and not be dependent on when the algo was last used. He even said that DigiByte and Myriad had the same problems and we fixed them! He cited this github repo for DigiByte:
It seems that the reason that this exploit was so lucrative was because the difficulty adjustment parameters were not enough to reduce the rewards the attacker recieved. Had the rewards per block adjusted at reasonable rate like we do in DGB then at least the rewards would have dropped significantly per block. The attacker was able to make off with around 60 million Verge which equals about 3.6 million dollars per today’s prices. The exploit used by the attacker depended on the fact that time stamps could be falsified firstly and secondly that the difficulty retargeting parameters were inadequate. Let’s cover how DigiShield works more in detail. One of the DigiByte devs gave us this post about 4 years ago now, and the topic deserves revisiting and updates! I had a hard time finding good new resources and information on the details of DigiShield so I hope you’ll appreciate this review! This is everything I found for now that I could understand hopefully I get more information later and I’ll update this post. Let’s go over some stuff on difficulty first then I’ll try giving you a way to visualise the way these systems work. First you have to understand that mining difficulty changes over time; it has to! Look at Bitcoin’s difficulty for example – Bitcoin difficulty over the past five months. As I covered in another post (An Introduction to DigiByte Difficulty in Bitcoin is readjusted every 2016 blocks which each last about 10 mins each. This can play out over a span of 2 weeks, and that’s why you see Bitcoin’s difficulty graph as a step graph. In general, the hash power in the network increases over time as more people want to mine Bitcoin and thus the difficulty must also increase so that rewards are proportional. The problem with non-dynamic difficulty adjustment is that it allows for pools of miners and or single entities to come into smaller coins and mine them continuously, they essentially get “free” or easily mined coins as the difficulty has not had time to adjust. This is not really a problem for Bitcoin or other large coins as they always have a lot of miners running on their chains but for smaller coins and a few years ago in crypto basically any coin other than Bitcoin was vulnerable. Once the miners had gotten their “free coins” they could then dump the chain and go mine something else – because the difficulty had adjusted. Often chains were left frozen or with very high fees and slow processing times as there was not enough hash power to mine the transactions. This was a big problem in the beginning with DigiByte and almost even killed DogeCoin. This is where our brilliant developers came in and created DigiShield (first known as MultiShield). These three articles are where most of my information came from for DigiShield I had to reread a the first one a few times to understand so please correct me if I make any mistakes! They are in order from most recent to oldest and also in order of relevance.
DigiShield is a system whereby the difficulty for mining DigiByte is adjusted dynamically. Every single block each at 15 seconds has difficulty adjusted for the available hashing power. This means that difficulty in DigiByte is as close as we can get to real time! There are other methods for adjusting difficulty, the first being the Bitcoin/Litecoin method (a moving average calculated every X number of blocks) then the Kimoto Gravity Well is another. The reason that DigiShield is so great is because the parameters are just right for the difficulty to be able to rise and fall in proportion to the amount of hash power available. Note that Verge used a difficulty adjustment protocol more similar to that of DigiByte than Bitcoin. Difficulty was adjusted every block at 30 seconds. So why was Verge vulnerable to this attack? As I stated before Verge had a bug that allowed for firstly the manipulation of time stamps, and secondly did not adjust difficulty ideally. You have to try to imagine that difficulty adjustment chases hashing power. This is because the hashing power on a chain can be seen as the “input” and the difficulty adjustment as the corresponding output. The adjustment or output created is thus dependent on the amount of hashing power input. DigiShield was designed so that increases in mining difficulty are slightly harder to result than decreases in mining difficulty. This asymmetrical approach allows for mining to be more stable on DigiByte than other coins who use a symmetrical approach. It is a very delicate balancing act which requires the right approach or else the system breaks! Either the chain may freeze if hash power increases and then dumps or mining rewards are too high because the difficulty is not set high enough! If you’ve ever taken any physics courses maybe one way you can understand DigiShield is if I were to define it as a dynamic asymmetrical oscillation dampener. What does this mean? Let’s cover it in simple terms, it’s difficult to understand and for me it was easier to visualise. Imagine something like this, click on it it’s a video: Caravan Weight Distribution – made easy. This is not a perfect analogy to what DigiShield does but I’ll explain my idea. The input (hashing power) and the output (difficulty adjustment) both result in oscillations of the mining reward. These two variables are what controls mining rewards! So that caravan shaking violently back and forth imagine those are mining rewards, the weights are the parameters used for difficulty adjustment and the man’s hand pushing on the system is the hashing power. Mining rewards move back and forth (up and down) depending on the weight distribution (difficulty adjustment parameters) and the strength of the push (the amount of hashing power input to the system). Here is a quote from the dev’s article. “The secret to DigiShield is an asymmetrical approach to difficulty re-targeting. With DigiShield, the difficulty is allowed to decrease in larger movements than it is allowed to increase from block to block. This keeps a blockchain from getting "stuck" i.e., not finding the next block for several hours following a major drop in the net hash of coin. It is all a balancing act. You need to allow the difficulty to increase enough between blocks to catch up to a sudden spike in net hash, but not enough to accidentally send the difficulty sky high when two miners get lucky and find blocks back to back.” AND to top it all off the solution to Verge’s time stamp manipulation bug is RIGHT HERE in DigiShield again! This was patched and in Digishield v3 problems #7 Here’s a direct quote: “Most DigiShield v3 implementations do not get data from the most recent blocks, but begin the averaging at the MTP, which is typically 6 blocks in the past. This is ostensibly done to prevent timestamp manipulation of the difficulty.” Moreover, DigiShield does not allow for one algorithm to mine more than 5 blocks in a row. If the next block comes in on the same algorithm then it would be blocked and would be handed off to the next algorithm. DigiShield is a beautiful delicate yet robust system designed to prevent abuse and allow stability in mining! Many coins have adopted out technology!
Verge Needs DigiShield NOW!
The attacker has been identified as IDCToken on the bitcointalk forums. He posted recently that there are two more exploits still available in Verge which would allow for similar attacks! He said this: “Can confirm it is still exploitable, will not abuse it futher myself but fix this problem immediately I'll give Verge some hours to solve this otherwise I'll make this public and another unpatchable problem.” - IDCToken DigiShield could have stopped the time stamp manipulation exploit, and stopped the attacker from getting unjust rewards! Maybe a look at Verge’s difficulty chart might give a good idea of what 1 single person was able to do to a coin worth about 1 billion dollars.
Edit - Made a few mistakes in understanding how Verge is mined I've updated the post and left the mistakes visible. Nothing else is changed and my point still stands Verge could stand to gain something from adopting DigiShield! Hi, I hope you’ve enjoyed my article! I tried to learn as much as I could on DigiShield because I thought it was an interesting question and to help put together our DGB paper! hopefully I made no mistakes and if I did please let me know. -Dereck de Mézquita I'm a student typing this stuff on my free time, help me pay for school?

Although be it that I don't have a complete mastery of the concept either, I will do my best to use my limited knowledge to explain what exactly the heck is going on with this mystical "Litecoin Mining" and the disappearance of AMD GPUs worldwide. What exactly is Litecoin mining? Litecoin mining, or cryptocurrency mining in general, is the use of processors to hash out a value and submit this work in something called "Proof of Work" that is mutually recognized. To put this in an analogy, think of a 3rd grade math classroom. The teacher writes a math problem on the board, say "2+3", and she tells the class to find the answer. Quickly, each student begins to work out the problem, and when a student thinks they've found the answer, they raise their hand and respond, "The answer is 5!". The teacher will then tell the student whether they are right or wrong, and the rest of the class will listen and understand that the one student got the answer right. Then they clap for him, recognizing his achievement and work needed to arrive to the answer. Now, in terms of mining, this difficulty is scaled to immense amounts, but the basic principle is the same. You, the miner, are the student trying to find the answer. The Litecoin master algorithm is the confirming teacher. And the rest of the miners are the other students in the classroom, recognizing your work. Litecoin itself is a derivative of Bitcoin, which is basically another cryptocurrency. Sources: Litecoin Website and Bitcoin (something like Litecoin) So what is so important about this answer? In reality, nothing. It just solves a math problem. But that's all the reason. When the Litecoin algorithm sees you've found the right answer and everybody agrees you found it (so no cheating!), then it will give you a "block reward". Like the teacher handing you a piece of candy for getting the right answer. This block reward contains an amount of Litecoins. What is a "Litecoin"? A Litecoin is a medal or proof of work done, and it is given through the reward system aforementioned. Litecoins are just numerical values stored inside of the "blockchain", which you can think of as the classroom. All of the players of this litecoin mining are located within this classroom, located within the blockchain. When everyone recognizes your work, you are given litecoins, which can only be accessed within wallets. You may think of litecoins as a currency, like pennies or nickels. They are something that we give value, yet do not have inherent value themselves. A paper bill is just paper unless we give it value. So what is a wallet? Wallets are where litecoins are stored, using a private key and a public key. This private key is a hash of base 58 that is completely randomized, such that only knowing both the private and public keys allows access to this wallet. The public key is shared with others who want to send you litecoins, while you keep the private key to yourself, which allows you to spend those litecoins. Now, the ultimate question: Why are they taking our graphics cards?! Ah yes. Now to talk about AMD GPUs. Litecoins use the scrypt algorithm, a memory and computation intensive algorithm that requires many cores and lots of fast RAM. Graphics cards fit both of these profiles perfectly. A graphics card has hundreds or thousands of computation cores, as well as lightning fast GDDR5 memory. As such, graphics cards are snatched up by miners wanting to create money out of thin air, which is basically what they're doing. But why AMD? Why not NVIDIA? AMD graphics cards are more efficient at moving bits than NVIDIA graphics cards, further explained here. All you really have to know if that the AMD architecture is much more efficient for cryptocurrency mining. But why NOW? Bitcoin/Litecoin has been around for awhile. Why are miners stealing our graphics cards NOW? Well, to put it bluntly, it's because people want to get rich. Recently, as further adoption by companies and the media coverage of cryptocurrencies, Litecoin price has skyrocketed. I'm talking magnitudes of 100 fold. Due to this rapid increase in value, miners have been rushing for more graphics card to make more money. If you take a look at this source, you can see that cryptocurrency mining profitability is insanely high compared to Bitcoin, which is Litecoin's main competitor. Look at the right column in the table that says "Profit Ratio vs. BTC". See the numbers in the 3000% range. Yeah, that's a lot of profitability that can be taken advantage of. Will we ever get our beloved 7950s back here in /buildapc? Q_Q Maybe. Delving deeper into what is litecoin, I'll now explain difficulty. As you find more of these answers, with more students working to find the answer to a math problem, the teacher must create more and more difficult math problems for the students to solve, else these little 3rd graders will solve them faster than the teacher has enough candy for. In litecoin mining, this equates to difficulty level. As the difficulty increase, litecoins are harder to hash out, and the rewards diminish. As more students/miners join the blockchain, mining will start to get less and less profitable. HOWEVER. If the price of litecoin skyrockets again, mining will be able to sustain profitability, and we may be out of AMD graphics card for a LONG, LONG TIME. Not to mention, once litecoin becomes unprofitable, if it indeed does, miners will move to other derivatives of cryptocurrencies, restarting the cycle and continuing to snatch up graphics cards. It is unlikely that this trend continues, but if it does, NVIDIA may be the only option for new gamers. Give me a TL;DR summary! I'll try my best. Poor people are sitting in a basement making money of out thin air using our graphics cards. They are making $12 a day per graphics card by basically only paying for electricity. This trend will continue for quite some time, meaning no more AMD graphics cards for a while. If you're a gamer, look towards NVIDIA, or be prepared to throw down a lot of cash. I obviously did not cover EVERYTHING in this post, but the main principles are there. If you want to delve deeper into this, I'd suggest doing your research and looking on the Bitcoin Forum. EDIT: Please check out /litecoin and /litecoinmining as well. Lots of good information.
BCH nov15-dec15 update . BCH moves along and claims its #4 place back on CMC
https://news.bitcoin.com/hash-wars-bch-proponents-face-a-new-dawn-in-the-battles-aftermath/ 35 days later after the fork, Bitcoin Cash supporters are working towards moving past the hash war that took place a little after the scheduled BCH upgrade on Nov. 15. Now both networks are operating and the Bitcoin Satoshi’s Vision (BSV) coin has its own price ticker and market capitalization listed on data sites like Coinmarketcap and Satoshi Pulse. A portion of crypto-trading platforms have now listed BSV as a separate currency and the entire ecosystem of exchanges, payment processors and a great majority of wallets have awarded the ABC side of the chain the BCH ticker. At the time of writing, the global average price for BCH is $144 after markets jumped 47 percent on Dec. 19. BSV spiked 18 percent this Tuesday and each coin is currently trading for $92 per token. Since the fork, the BCH network hashrate has dropped considerably, even more so than the 50 percent loss BTC suffered this past month. Average hashrates for a great number of SHA-256 algorithm coins have endured deep drops in processing power according to global statistics. The Bitcoin Cash hashrate used to command a rough average of 5 exahash per second (EH/s), but now only captures 1 EH/s to 850 petahash per second (PH/s) on a daily basis throughout this month. On the bright side, the BCH network has been 5-8 percent more profitable to mine than BTC over the last two days. Further, BCH has amassed a large swathe of different mining pools that are processing BCH blocks on a regular basis. This includes Viabtc, Btc.com, Antpool, Multipool, Bitcoin.com, Btc.top, Waterhole, Copernicus, P2pool, Ckpool, and some other unknown mining entities as well. Another BCH metric that has halved since the fork on Nov. 15 is the cryptocurrency’s daily transaction rate over the last month. Before, bitcoin cash transactions per day were about 20,000-25,000, whereas today that number stands at roughly 9,750 over the course of the last 24 hours. Over the last three weeks, the BCH daily transaction rate has been averaging 10k per day, with a few instances of 15k-22k spikes here and there. There has been a steady increase in daily transactions week after week, and with 99 percent of BCH infrastructure back in order, this should continue. A good example of this behavior is the increase in BCH price and trade volume on exchanges over the last few weeks. Pre-fork BCH trade volumes captured anywhere between $400-900 million worth of global trades every day. After the fork, this statistic dropped to around $50-100 million daily on global exchanges. This was because some cryptocurrency trading platforms with a ton of bitcoin cash liquidity had paused BCH transactions and some exchanges halted trading. Week after week, however, global BCH trade volume has been steadily increasing on exchanges like Upbit, Binance, Huobi, Lbank, and Coinbase Pro. With the 40 percent increase over the last 24 hours, BCH trade volume has jumped to over $400 million in global trades on Dec. 19. At the time of publication, this makes BCH the seventh most traded digital asset out of the entire crypto economy. The Bitcoin Cash community had also suffered from daily battles on Reddit’s btc forum and social media platforms like Twitter. A good portion of the trolling and infighting seems to have quietened down, and most BCH supporters are just trying to move forward. There’s been plenty of developments since the fork, with projects like Electron Cash, Honest Cash, Cash Shuffle, and Openswap adding more utility to the BCH network. Furthermore, BCH enthusiasts look forward to the upcoming BCH upgrades that are under discussion and they can track the code’s development too. For now, BCH supporters are extremely pleased that the fork is behind them and are thrilled to reclaim fourth position among all cryptocurrency market capitalizations.
Clearing up some confusion about cryptocurrencies, mining and when prices will go down.
I spend my last 6 months in a lot of cryptocurrency Reddits and informed myself about the topic. I read a lot of misinformation in the non crypto Reddits every day and because of that I am making this post to clear some things up and explain everything. Sorry for the wall of text, there will be a tldr; at the end
How do mining profits work?
The Ethereum network pays out people who mine for them in Ethereum. The total daily amount of Ethereum giving out is more or less constant for now which means that if only a single person mines he gets everything, if a million person mine with the same hash power behind them everyone gets 1/1,000,000 of the reward, the reward itself does NOT increase, only the price of the ETH can increase. Normally people would buy more GPUs until they reach a point of only a small profit compared to the energy costs and it would a reach a point of balance between total network hashrate and profit in USD (like it was in the last 3-4 years). The problem is that the price spiked multiple times way too fast and GPU manufacturing can't keep up which causes GPU prices to spike and delays this point of balance which results in MASSIVE profits for everyone who mines because the hashing power "supply" is capped. We are talking about 100$ a month with a SINGLE RX 480 right now (80$+ with power cost included).
When will it stop?
Actually quite soon (yay). This is sadly a truth that not many miners know of (not to mention some are delusional... you will find them in the comments) and very few people think about. Even the popular Youtube channels have no idea about this. Before I come to the end of GPU mining first there are some numbers.
How many GPUs are out there and how much are the total profits?
The current network hashrate is about 191TH/s and a total daily reward paid of 31,239,969$ in the last 24 hours. Because a single RX 480 gets about 28MH/s (pretty much average), we have about 6,821,428 GPUs mining ONLY Ethereum right now. If you every wondered how much money you need for a global GPU shortage the answer is about 30 million dollar daily.
Can you finally tell us when and how it stops? I want to play pubg!
Ok ok... the thing is the Ethereum network doesn't need your GPU power. It only uses it as a spam filter to make it harder to manipulate the network. You would need over 50% of the total hashrate to reliably fake transactions, think of it as a giant google captcha. You can easily replace that captcha with another one and this is exactly what Ethereum does in the near future. Proof of stake means instead of wasting GPU power you just stake your Ethereum and the more of your Ethereum you invest the more voting rights and rewards you get. If you are caught trying to cheat your whole money gets confiscated and donated to everyone else depending on their voting rights. Full proof of stake will probably be implemented late 2018 but just to be fair it already got delayed multiple times so there is no clear 100% date for it yet.
So... Ethereum fires all the miners, wont miners just mine something else?
This is where the misconception starts. There is actually a second point of balance in all of this. All cryptocurrencies will always divide all the hashing power between them until they all reach about the same profit (people always switch to what gives the most profit). It may seem like there are a lot of profitable cryptocurrencies to mine but that is actually an illusion. Many of the smaller coins would be unprofitable after a few thousand GPUs because their total $ reward giving out daily is pretty small. The thing is nobody mines something that gives less profit so they switch. To sum it up Ethereum is basically the minimum payment job and everyone who goes below that wont find anyone willing to do the job until they get more profitable than Ethereum. Now what happens if 6.8 MILLION RX 480 are jobless after a single update? They will all start mining something else. The problem is Ethereum has a GIANT majority in hashrate and all other mineable cryptocurrencies combined can't be profitable after Ethereum switches even if their prices spike by 10x.
It can't be that bad...
OH HELL YEAH IT IS THAT BAD! Every heard of Monero? It is the cryptocurrency that caused the RX Vega shortage. Any idea on how much daily rewards they give out? A giant 1,504,249$ in the last 24 hours. Yes that is 20.7 times less and we are talking about the second biggest mineable coin out there. As soon as Ethereum fires all the miners everything will collapse and profit will turn NEGATIVE for a while unless you have free power. Q4 2018 is the end of mining for probably ever. Because the Ethereum code is open source and everyone can use it there will most likely be more coins that follow proof of stake after that (there already are some that already have it) so mining will most likely never come back.
Why the switch to proof of stake?
There are many benefits. It consumes A LOT less power, it is most likely faster and people who hodl Ethereum get more Ethereum for just having it. Free interest rate hype! But the most important thing about this is that miners control the currency and every update to it. Sadly they don't have the same interests as people who want the crypto to succeed and improve. For example Bitcoin's block size is kept at 1mb even though increasing it was always the plan since 2009. Why? It's very simple. You can only fit X amount of transactions in 1mb and if it gets more than that only people who pay more get their transactions in faster which means more fews are being paid to the miners. While they make a fortune the currency suffers with spikes to 50$ for a SINGLE transaction (currently it's 18$). If the power goes to the ones having the currency they are directly interested in the well being of the currency which is better for everyone.
So... what does all of this actually mean?
We will get the biggest GPU mass sell off in the history of the technology itself. I wouldn't be surprised to find a RX 480 for 100$ in December. Miners already made the price of the GPU back multiple times, they don't care about the price if they get at least something. This will be a GREAT time for buying GPUs. It already happened once in 2013? when ASIC miners got introduced for Bitcoin mining and all R9 290(x) got dumped on the market because they went from awesome miners to completely useless overnight. This time will be much bigger though because of the sheer amount of GPUs used for mining.
AMD's and Nvidia's part in this
AMD did ramp up production last time with the r9 290(x) and got completely rekt. They couldn't sell the GPUs anymore and the used r9 290(x) were way too cheap to compete with. This time they are smarter and they just make as much as they can without investing too much while basically selling everything they produce for almost a whole year. Nvidia is about the same right now, they are just making bank without risking much. If you ever wondered why the 1070ti exists, it is basically a mining only GPU. The 1080 is horrible for Ethereum mining because of GDDR5X timings but the 1070ti has the same GPU power with GDDR5 non x. They only made this for more profit when selling to miners.... yet no reviewer called them out for this to my knowledge.
GPU prices will crash hard and the used market will have laughable low prices. These GPUs actually run undervolted, underclocked and at a low temperature the whole time because the bottleneck is the memory speed which means they are in EXCELLENT condition. Maybe their BIOS got flashed for better memory timing but you can just switch to the second BIOS or flash it back to normals. These will the GREAT to buy. Note that r9 290(x) and 390(x) GPUs should be avoided because they have such an overkill memory setup that their GPU core is the bottleneck (-> overclocked, overvolted and run at 90c+).
How will Nvidia react?
Well they will have a problem. Nobody will buy a 1180 if they can get a GTX 1080 for 200$ compared to something like 600$. Especially if Nvidia releases the 1180 while mining is still a thing. I guess they will wait with the 1180 or release a 1280 shortly after mining died with a really competitive price (if AMD can't compete they will just compete with themself...). Just think of the GTX 970 which got released with a 299$ MSRP and got actually sold at that price!
This got way longer than expected... well I hope you learned something. Just comment if you want to correct something or have a question. Most of these are assumptions based on thinking so none of this has to happen but is in my opinion very likely to happen. tldr; Because Ethereum has almost all of the GPU power behind it and will fire all the miners in around Q4 2018 with the switch to proof of stake there will be a huge excess of GPU power and prices will crash hard. edit: if you only care about numbers and facts and want a better distinction between assumptions and facts read my other comment https://www.reddit.com/pcmasterrace/comments/7rqkmo/clearing_up_some_confusion_about_cryptocurrencies/dsyzg6b/
Due to an oversized solar array, I have about 10 kW of unused energy per hour during daylight hours. How much can you make per kWh in Bitcoin assuming your electrical cost is zero? If part of that answer is "it depends on your mining hardware" then could someone supply a table showing the current market cost for each kind of miner and the expected power draw in kW of each model? Which mining hardware would give the most mining power per dollar spent? This mining profitability calculator seems to give the main variables. https://www.coinwarz.com/calculators/bitcoin-mining-calculato?h=23000.00&p=1541.00&pc=0.0&pf=0.00&d=5106422924659.82000000&r=12.50000000&er=3895.50000000&hc=0.00 Do I just need to plug in my expected hash rate, energy consumption in watts, and electrical cost of zero? This article seems to suggest that in Jan 2018 the break-even price was $3900 per bitcoin, which corresponded to an electrical cost of 3 cents per kWh. https://medium.com/@hodlmodel/breakeven-price-of-btc-mining-i-bitmains-49-hashrate-694a5699fa37 Obviously that was a different world than today, but I wonder if things would be migrating - when bitcoin pricing is falling sharply - towards that break-even electrical cost of 3 cents per kWh. If yes, mining bitcoin with the available free electricity seems like a poor investment.
The connection between the LTC price surge since mid november and the new Batch of Bitmain Miners.
I think its time that people understand a bit more, and post memes that explain nothing a bit less. There is too many newbies in crypto now who don't understand anything and just think Litecoin is great because its expensive. Take a look at these 3 things: Available Mining hardware The Litecoin mining difficulty The Litecoin price Available Mining Hardware Bitmain sold their last big batch of miners in early summer 2017, since then LTC Miners have been sold out. Suddenly mid november, LTC Miners were available again on Bitmain's Internet site. The Litecoin mining difficulty It takes a while for Bitmain to distribute all their miners, at the end of the summer it seems that the summer batch of miners has found their new owners. The Litecoin Difficulty stopped rising and was steady at a plateau. Roughly 4 ASIC miners were necessary to mine one LTC in 24h until mid november. Its an open secret that Bitmain "tests" their miners before they send them to their clients, and the day they started selling their new batch, they started "testing" it as well. You can see very clear how the difficulty jumped up and is growing steadily ever since. From Friday to Saturday, the LTC difficulty jumped up from 1.7Mio to 1.9Mio, it's the biggest jump in difficulty this year if I haven't overlooked something. Today, the mining profitability outcome/harvest is at almost 50% of what it was before the day Bitmain started "testing" their new miners. Roughly 8 ASIC miners are now necessary to mine one LTC in 24h. The Litecoin price Not accounting for the spikes here and there, the LTC price this summer looked similar to the difficulty chart. During the summer, the price was quite steady at a plateau. This changed though in november. The price started to rise steadily. From Friday to Saturday, the LTC price jumped up 50%, also the biggest jump in a pretty short time that we have seen this year. I hope you are starting to see what pushes the price up lately. Its not the Goku/Vegeta Memes of the new "coalition" between Bitcoin and Litecoin. Its not Charlie Lee's twitter about LTC acceptance at Bitrefill.com. Its a necessary reaction to keep the network save and alive, because if profitability goes down to 0, miners will stop mining. Have a nice weekend and enjoy the price spike. edit: I am not trying to proof that general demand does not push the price up! LTC is available in limited quantities, so of course there is an upward trend with increased demand. I am trying to show you one reason for sudden price increases (and decreases) that many newbies are not aware of. edit2 2 corrections for clarity: changed profitability to outcome/harvest and put brackets around decreases, because my observations are actually that the price has to adjust upwards with increase in difficulty. I have not enough evidence that it goes downwards as well with decreased difficulty. Profitability of LTC mining actually stayed the same since mid november due to the adjustment of the price to the increased difficulty. edit 3 Users are commenting that the difficulty follows the price. I understand very well that when a coin becomes very profitable to mine, people jump on it. But how do you explain this then? Until the 5th of December, the hash rate increased slowly. From 5th to the 8th of December the LTC hash rate increased to 250% of what it was was before. The difficulty jumped up on the 6th of December from 1,3 to 1,7mio. And on the 9th of December from 1,7 to 2,4mio. So it increased to 200%, which means the profitability sunk to 50%. The LTC price was steady until the 8th of December at 95$. From the 8th to the 9th of December it went straight up to 150$. A price spike right after everybody went home or drinking on a friday? The price went up after the difficulty doubled, not before. I'm just reading charts and try to make sense of them. Just saying "no" without having another explanation is just not very convincing.
Wafflepool and Multipool together control over 50% of the global hashrate. Shibes, this is a serious problem.
tl;dr: MFW I see a threat to Dogecoin: http://i.imgur.com/vtF2yU6.gif As of this writing, Wafflepool (with 37.66% of the network hashrate) and Multipool (with 18.74% of the network hashrate), control 56.34% of the network hash rate. Source: https://pools.rapidhash.net/ This is a problem Are these pools likely to collude to 51% our beloved coin? Not likely at all. Does every human person with access to two computers on the Internet practice perfect security when it comes to authentication and server hardening? Not likely at all. The 51% attack is now quite possible if someone compromises just two computers: the controllers at the top of these two pool hierarchies. +GoodShibe talked about decentralizing hashrate last week in Of Wolves and Weasels. In response, I put up a quick and admittedly quite imperfect project to help explain and combat centralization by promoting ubiquitous CPU mining on existing, unused hardware. Dogecoin needs to be peer-to-peer, for real, to survive The 51% Attack is not theoretical -- read up on the attack last June against Feathercoin. They were unprepared for this and I believe as a result of this event, Feathercoin is now all but dead. Today, the attacker(s) is/are still unknown and presumably at large. I don't know how to solve this. I know there are many, many smart cryptocoin experts on this subreddit. Cheer me up so I can go back to goofing off with this play-pretend-but-really-real-mostly cryptocurrency project. Thanks! edit: first 26 minutes of this post, 3 uprockets, 3 downdigs. funky i guess i have to gun for the controversial tab instead of the hot tab. edit1: first 21 hours of this post, tons of uprockets and tips. Thanks everyone! I learned a lot about hashrate and malicious intent, and I hope others did, too! And here I thought the 0 score was going to doom this post. For more like this, visit /panicdoge!
Why the price of DOGE is falling and will continue to. SUCH MAFFS. SO LOGIC. WOW.
TLDR; Dogecoin is one of the most profitable coins to mine, so people are mining and dumping for profit. Will probably still drop by ~10-25%. Woof.http://i.imgur.com/NRVOtRI.jpg A lot of people are posting about the price of Dogecoin and are concerned with its price. There is speculation that is misleading and not backed up by much theory. It’s not just as simple as supply and demand, panic selling or the line of best fit on a graph. Let’s look at the maths and see why the coin is dropping so rapidly and why now. MAFFS The difficulty of mining a block of DOGE currently ranged from 300-400 , the higher this goes the less coin you will mine. To make things simple let’s run an example: Assume you have 1000kHash of digging power; with that you could mine at the current difficulty level approx. 30,000 DOGE a day ! The value of Dogecoin is tightly tied to Bitcoin, we first convert it to BTC and sell that. The price for a single DOGE is roughly 0.00000040 BTC  and a BTC is worth around $850 . In our 24 hours of work we earn $10.20 (0.00000040 * 30000 * 850). Wow. Such pawfit. Now compare this to the ‘standard’ of scrypt mining, Litecoin. For the same time and strength of your digging you would yield around $8.50. If you were only interested in profit you would mine DOGE and sell it because it made you the most profit for your hashrate. A lot of people are doing this, including multicoin pools, they mine the most profitable coin and convert it to BTC. It’s simply efficient. This means that there is a huge dump of coin on the market and the price will fall. SPECULATION When will the coin stop dropping in price? When it is no longer the most profitable coin, so probably around 0.00000030 to 0.00000035 BTC. At this price the profitability is too low to reward these types of miners. Alternatively, if the difficulty was to increase then the amount of coins earned (EDIT: coins per person, overall supply per time is constant! More miners = lower split per miner) would be reduced and the profit margins would also decrease, I’d estimate the difficulty would need to be around 450 to 500 to balance out. The difficulty increases if more people mine the coin, and at this point that will be depending on popularity. Sure a few people are panic selling but comparatively this is a drop in the ocean and even so it will just help the coin reach its stable price a little faster. Anybody who wants to see the coin succeed is already doing what they need to, they are not concerned with the price, remember to have fun! Another point to note is that over the last few days the price of BTC has risen, and so even if the price of DOGE was stable the exchange ratio for DOGE->BTC would still show a fall – this is slightly misleading and the fall in price is not as hard as it seems! So what can you do? Wait. The price will level out and over time the difficulty should increase with popularity and in around 1-2 months the reward will halve, I'd expect a big peak in price around that time. The coin is young and popular; it needs to learn the Earth before it can go to the Moon.
Let's talk about the power behind merged mining. (Auxiliary proof of work - AuxPOW) Very simple: you mine for instance Litecoin and can mine at the same time Viacoin without losing hashrate. But we are going to make an example. Look at the Hashrate of Viacoin let say it is around 50 TH/s. https://chainz.cryptoid.info/via/ We take the Antminer L3+ as the miner for the whole Viacoin network. The Antminer L3+ produces around 500 MH/s and it uses 800 watts. This means that we need 100.000 Antminers to come at a network hashrate of 50 TH/s.The whole system of 100.000 Antminers are using 80.000.000 watts. (800 watt x 100.000) These 80.000.000 watts x 24 Hours will result in 1920000 kWh.Let say the power costs are $0.15 per kWh is a total-cost of $12000 per HOUR ! To run the Viacoin network on your own with 50 TH/s will give you a electricity bill of $288,000.00 per DAY ! And than we even not talked about the equipment costs. https://www.coinwarz.com/calculators/viacoin-mining-calculato?h=50000000000.00&p=80000000&pc=0.15&pf=0.00&d=329994.01552825&r=0.03906250&er=0.00008391&btcer=3714.30000000&hc=0.00 In the link i put in all the correct data and you can see it for your self, what it actually will costs to run the whole Viacoin network. -------------------- At a price as Viacoin is today, you will lose 105 M dollar in 1 year to run the network. If Viacoin was not AuxPOW the price for 1 Viacoin should be around 2400 dollars each, just to make the mining profitable. And with this in mind you can see the enormous benefits behind Viacoin's merged mining. It is not only secure but it also brings sustainability, and provides, that you are paying a fair price for your coin. Not a single company has benefits to give Viacoin an artificial price, that's why you pay for Viacoin $0,30 and not $2400,- And with a lot of cryptocurrencies there is a lot of money involved, and the actual buyers are paying the price. When you buy Viacoin you know for sure that the price is originated by supply and demand, and personally with other cryptocurrencies i have so my doubts. Other article that you might be interested in to read about merged mining:
And than we can talk about the huge energy-costs of mining, and people will say yes but proof of stake and masternodes...... The problem with those algorithms is that it creates an elite-status to early investors, those people are untouchable until they decide to step out, and there even can be SIMILARITIES found with a ponzi-scheme, i am not saying it is a 1 on 1 ponzi. Let say someone paid 5 dollar for a masternode and the 10th man paid $500 and the 10000th man paid $500000 dollars because this is what happens, the first people are untouchable and only generates money, the last is paying a big price and can wait 300 years to earn his investment back.Same is for proof of stake it only generates money for the team behind the coin or early investors. It only can be considered fair and efficient when the pay-out for those algorithms is ZERO. ---------- Than you have people that say, yes but than cryptocurrency in general is a ponzi, well... Do you consider gold as a ponzi? I know for sure those people who bought gold, didnt get any extra gold by only holding it.And the same you can apply on POW. 1.WORK PAYS 2.DETERMINATION PAYS But we were talking about the energy costs. --------- Energy costs. A lot of people are talking about the energy waste of proof of work systems, it is a point, but their is one big ''but''. Can you name me one industry where there is no environmental footprint? I personally realy dont know. When you drive a car, metal must mined and gasoline must come out of the ground, when you in a plain and go on vacation etc.. etc.. Not going to deep in this stuff because it is endless. But those same people are saying that proof of work is a waste of energy, while they fly around the world, and than they suddenly don't care about the environmental footprint they as a human leave behind and the flight industry they support? I am in fact for a greener world, but for that, there a change is needed not only in the world industry but also in the world economy. I see AuxPOW as a green step to an ''existing problem'' because it thrives only on the energy from other blockchains, and not use electricity on it's own. And when the blockchain industry evolves, their will be new solutions, and when Bitcoin, Litecoin or any other can implement such new solutions, to this problem, than also Viacoin can implement it. Thank you for reading.
Multipool- A pool of miners that automatically mine the least difficult, most valued and easily tradable cyptocurrency, at that time. These pools automatically! switch between coins as they become more valuable to mine. One of their favorites just happens to be Doge, alongside aurora and litecoin. They do this to maximize their daily mining profits. These coins are then automatically! sold for bitcoin on an exchange; dumping said coins for whatever they can get at the time! <-- For those that don't know :) If a coin becomes the target of this, its value can be pushed down significantly! At the same time said coins difficulty increases because of the huge surge in hashing power by these multipools. Making it more difficult for dedicated miners. In fact, this has completely destroyed smaller coins before. http://www.coinwarz.com/cryptocurrency/coins/dogecoin <-- If you look at the difficulty chart here, you will notice that it looks like a saw. This is because we are being targeted repeatably by multipools. These pools are causing our mining difficulty to jump from 900 to 1200 repeatedly (70gh to 100gh, global hashrate) This is a 25-30% increase over the entire global hashrate of all of the doge being mined everwhere!! i.e. lets say we mine 360 mil Doge a day(what I saw quoted awhile ago) and 25% of that is being sold as soon as its mined. That would roughly be 90,000,000 coins being sold and dumped immediately! So vast amounts of doge are being traded automatically for bitcoin and driving down our value. If you put a massive supply of anything to sell on a market, the supply outweighs demand and the price falls Thankfully, another halvening is just over a month away. This will make sure that we aren't one of the most valuable coins to mine and as such wont be targeted by multipools! Well, at least not until our value goes way up! If you can, buy doge now!, You will never see it this cheap again after the next halvening in april. tl;dr Stoopid multipools! I shake my fist at thee!
Hi, it’s some weeks that I’m getting into Monero and I really see a great future for it. My problem is that I have a very low budget so my mining capability is a joke (around 80 h/s). I cannot help this coin to grow by mining it, so I’m making this FAQ hoping that can be useful for new users. If you want to support me, the tip jar is at the end of this post. Thank you!
I noticed a lot of confusion around Monero. Many of the most asked question are basically the same , so I collected some of them from /monero, /moneromining and monero.stackexchange and I made this Monero Faq. Please feel free to suggest any new frequently asked question or correction/modification/ (also about the grammar, my english is not very good), i’d like to keep this post updated.
Minergate is known for being linked to Bytecoin (read here and here ) and many users are noticing lower or differences in hashrates when using other miners (just make a research using the word “minergate” here on reddit). don’t be fooled by the nice graphical interface.
New people please read this. [upvote for visibility please]
I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can. Preface Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here. If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier. Mining. What is it? Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section. Mining Hardware While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much. Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it. So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy. Should I mine? Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats PCPartPicker part list / Price breakdown by merchant / Benchmarks
Prices include shipping, taxes, and discounts when available.

Estimated Hashrate (with GPU overclocking) : 1900 KH/s Hardware Fundamentals CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with. RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory. HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats) GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like. PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption. MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less. PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied. When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info. Mining Software Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head) Mining Pools Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself. How do I connect to a pool? Most pools will give you a tutorial on how to but the basics are as follows:
Signup for a pool
Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine: Hardware cost: The cost of your physical hardware to run this whole operation. Power: Measured in $/KwH is also known as the operating cost. Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon. Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously. Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones. coinwarz I like this one cause it is simple. The fields are self explanatory. Try it. bitcoinwisdom I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account. Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it! More Below.
Bitcoin mining difficulty up another 24% in just the last 30 days!
A year ago the hashpower needed to mine Bitcoin was insane, the network was considered unbreakable. But its continued to double every few months. This is an indicator that the $ cost for many miners has continued to increase, yet investment into mining continues to thrive. Mining is basically an entire sub economy of the tech sector creating massive amounts of wealth and jobs. Here's a link showing charts for the increase in hash power...it shocked me in January and I didnt think it would just keep going up so much during this bear market. https://www.coinwarz.com/difficulty-charts/bitcoin-difficulty-chart With so many questions about miner cost influencing supply and thus price, I'd like to hear your thoughts. If hashpower doubles again, the price support will likely gone up? Seeing as the 2014 crash had essentially no miner investment on this scale, its logical to assume that this is a game changer that continues to evolve. Even the people getting free hydro will start to be squeezed out with these difficulty levels. It reminds me of the way the diamond miners can control supply to influence price. Thoughts?
I want to argue that the value of bitcoin can be asserted by the cost to mine it. It could be less than that, but it doesn't make sense that it would be more than that. At current difficulty, an antminer s9 can mine 0.064 BTC/month. Lets say it cost you $1500 to buy and setup the S9 and it will last you 15 months (a conservative estimate); so every month the setup costs you $1500/15 = $100. Electricity costs $0.15/kWh. At 1300 W, it is $140.40/month. Thus, total monthly cost is $240, and income is 0.064 BTC. This means a BTC costs $240/0.064 = $3750 You could change the variables and get a fair future estimate. Say, if difficulty becomes 2x by the end of next year, your cost will become 2x, or $7500/BTC. ref: https://www.coinwarz.com/calculators/bitcoin-mining-calculato?h=13500.00&p=1300.00&pc=0.15&pf=0.5&d=1590896927258.08000000&r=12.50000000&er=18885.10000000&hc=1500 So at $18k, definitely a bubble!
Awhile ago, someone shared this, which is nice : https://coinmarketcap.com/new/ I have also went to Coinwarz and while you can click a drop down that says "Network Hash Rate" there are still images on the coins with no total hash rate listed. Right now I have some stuff in the shop and only have a GTX970 I remember the fun I had mining electroneum the first 24 hours it was open .. It was an absolute blast. It alse ended up making goo money - even though I know most coins will not ... I can't see t find a list of mineable coins that are new .. What would e PERFECT is if I could select a drop dow box by type of hashing ... then the coins were listed top to bottom in order of totl hash rates for the network ... I want to try solo mining for a week for the hell of it and find a block on my own .. Yeah I know I won't get anything with a GTX970 - but it's a down week ... and I want to have fun Anyone know anything like this ? I know you have bitcoin forum with [ANN] threads for ICO and the such, but I don't care if they are having a ICO. I want literally brand new coins to mine lol .. Anyone, any ideas ? Someone gave me a REAL good lick a while ago but can't find it in my bookmarks
