Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners
Thank you for inviting Horizen to the GPU mining AMA! ZEN had a great run of GPU mining that lasted well over a year, and brought lots of value to the early Zclassic miners. It is mined using Equihash protocol, and there have been ASIC miners available for the algorithm since about June of 2018. GPU mining is not really profitable for Horizen at this point in time. We’ve got a lot of miners in the Horizen community, and many GPU miners also buy ASIC miners. Happy to talk about algorithm changes, security, and any other aspect of mining in the questions below. There are also links to the Horizen website, blog post, etc. below. So, if I’m not here to ask you to mine, hold, and love ZEN, what can I offer? Notes on some of the lessons I’ve learned about maximizing mining profitability. An update on Horizen - there is life after moving on from GPU mining. As well as answering your questions during the next 7 days. _____________________________________________________________________________________________________
Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners
Author: Rolf Versluis - co-founder of Horizen
In GPU mining, just like in many of the activities involved with Bitcoin and cryptocurrencies, there is both a cycle and a progression. The Bitcoin price cycle is fairly steady, and by creating a personal handbook of actions to take during the cycle, GPU miners can maximize their profitability. Maximizing profitability isn't the only aspect of GPU mining that is important, of course, but it is helpful to be able to invest in new hardware, and be able to have enough time to spend on building and maintaining the GPU miners. If it was a constant process that also involved losing money, then it wouldn't be as much fun.
For a given mining algorithm, there is definitely a technology progression. We can look back on the technology that was used to mine Bitcoin and see how it first started off as Central Processing Unit (CPU) mining, then it moved to Graphical Processing Unit (GPU) mining, then Field Programmable Gate Array (FPGA), and then Application Specific Integrated Circuit (ASIC). Throughout this evolution we have witnessed a variety of unsavory business practices that unfortunately still happen on occasion, like ASIC Miner manufacturers taking pre-orders 6 months in advance, GPU manufacturers creating commercial cards for large farms that are difficult for retail customers to secure and ASIC Miner manufacturers mining on gear for months before making it available for sale. When a new crypto-currency is created, in many cases a new mining algorithm is created also. This is important, because if an existing algorithm was used, the coin would be open to a 51% attack from day one, and may not even be able to build a valid blockchain. Because there's such a focus on profitable software, developers for GPU mining applications are usually able to write a mining application fairly rapidly, then iterate it to the limit of current GPU technology. If it looks like a promising new cryptocurrency, FPGA stream developers and ASIC Hardware Developers start working on their designs at the same time. The people who create the hashing algorithms run by the miners are usually not very familiar with the design capabilities of Hardware manufacturers. Building application-specific semiconductors is an industry that's almost 60 years old now, and FPGA’s have been around for almost 35 years. This is an industry that has very experienced engineers using advanced design and modeling tools. Promising cryptocurrencies are usually ones that are deploying new technology, or going after a big market, and who have at least a team of talented software developers. In the best case, the project has a full-stack business team involving development, project management, systems administration, marketing, sales, and leadership. This is the type of project that attracts early investment from the market, which will drive the price of the coin up significantly in the first year. For any cryptocurrency that's a worthwhile investment of time, money, and electricity for the hashing, there will be a ASIC miners developed for it. Instead of fighting this technology progression, GPU miners may be better off recognizing it as inevitable, and taking advantage of the cryptocurrency cycle to maximize GPU mining profitability instead.
Cryptocurrency Price Cycle
For quality crypto projects, in addition to the one-way technology progression of CPU -> GPU -> FPGA -> ASIC, there is an upward price progression. More importantly, there is a cryptocurrency price cycle that oscillates around an overall upgrade price progression. Plotted against time, a cycle with an upward progressions looks like a sine wave with an ever increasing average value, which is what we see so far with the Bitcoin price. Cryptocurrency price cycle and progression for miners This means mining promising new cryptocurrencies with GPU miners, holding them as the price rises, and being ready to sell a significant portion in the first year. Just about every cryptocurrency is going to have a sharp price rise at some point, whether through institutional investor interest or by being the target of a pump-and-dump operation. It’s especially likely in the first year, while the supply is low and there is not much trading volume or liquidity on exchanges. Miners need to operate in the world of government money, as well as cryptocurrency. The people who run mining businesses at some point have to start selling their mining proceeds to pay the bills, and to buy new equipment as the existing equipment becomes obsolete. Working to maximize profitability means more than just mining new cryptocurrencies, it also means learning when to sell and how to manage money.
Managing Cash for Miners
The worst thing that can happen to a business is to run out of cash. When that happens, the business usually shuts down and goes into bankruptcy. Sometimes an investor comes in and picks up the pieces, but at the point the former owners become employees. There are two sides to managing cash - one is earning it, the other is spending it, and the cryptocurrency price cycle can tell the GPU miner when it is the best time to do certain things. A market top and bottom is easy to recognize in hindsight, and harder to see when in the middle of it. Even if a miner is able to recognize the tops and bottoms, it is difficult to act when there is so much hype and positivity at the top of the cycle, and so much gloom and doom at the bottom. A decent rule of thumb for the last few cycles appears to be that at the top and bottom of the cycle BTC is 10x as expensive compared to USD as the last cycle. Newer crypto projects tend to have bigger price swings than Bitcoin, and during the rising of the pricing cycle there is the possibility that an altcoin will have a rise to 100x its starting price. Taking profits from selling altcoins during the rise is important, but so is maintaining a reserve. In order to catch a 100x move, it may be worth the risk to put some of the altcoin on an exchange and set a very high limit order. For the larger cryptocurrencies like Bitcoin it is important to set trailing sell stops on the way up, and to not buy back in for at least a month if a sell stop gets triggered. Being able to read price charts, see support and resistance areas for price, and knowing how to set sell orders are an important part of mining profitability.
Actions to Take During the Cycle
As the cycle starts to rise from the bottom, this is a good time to buy mining hardware - it will be inexpensive. Also to mine and buy altcoins, which are usually the first to see a price rise, and will have larger price increases than Bitcoin. On the rise of the cycle, this is a good time to see which altcoins are doing well from a project fundamentals standpoint, and which ones look like they are undergoing accumulation from investors. Halfway through the rise of the cycle is the time to start selling altcoins for the larger project cryptos like Bitcoin. Miners will miss some of the profit at the top of the cycle, but will not run out of cash by doing this. This is also the time to stop buying mining hardware. Don’t worry, you’ll be able to pick up that same hardware used for a fraction of the price at the next bottom. As the price nears the top of the cycle, sell enough Bitcoin and other cryptocurrencies to meet the following projected costs:
Mining electricity costs for the next 12 months
Planned investment into new miners for the next cycle
Additional funds needed for things like supporting a family or buying a Lambo
Taxes on all the capital gains from the sale of cryptocurrencies
It may be worth selling 70-90% of crypto holdings, maintaining a reserve in case there is second upward move caused by government bankruptcies. But selling a large part of the crypto is helpful to maintaining profitability and having enough cash reserves to make it through the bottom part of the next cycle. As the cycle has peaked and starts to decline, this is a good time to start investing in mining facilities and other infrastructure, brush up on trading skills, count your winnings, and take some vacation. At the bottom of the cycle, it is time to start buying both used and new mining equipment. The bottom can be hard to recognize. If you can continue to mine all the way through bottom part of the cryptocurrency pricing cycle, paying with the funds sold near the top, you will have a profitable and enjoyable cryptocurrency mining business. Any cryptocurrency you are able to hold onto will benefit from the price progression in the next higher cycle phase.
An Update on Horizen - formerly ZenCash
The team at Horizen recognizes the important part that GPU miners played in the early success of Zclassic and ZenCash, and there is always a welcoming attitude to any of ZEN miners, past and present. About 1 year after ZenCash launched, ASIC miners became available for the Equihash algorithm. Looking at a chart of mining difficulty over time shows when it was time for GPU miners to move to mining other cryptocurrencies. Horizen Historical Block Difficulty Graph Looking at the hashrate chart, it is straightforward to see that ASIC miners were deployed starting June 2018. It appears that there was a jump in mining hashrate in October of 2017. This may have been larger GPU farms switching over to mine Horizen, FPGA’s on the network, or early version of Equihash ASIC miners that were kept private. The team understands the importance of the cryptocurrency price cycle as it affects the funds from the Horizen treasury and the investments that can be made. 20% of each block mined is sent to the Horizen non-profit foundation for use to improve the project. Just like miners have to manage money, the team has to decide whether to spend funds when the price is high or convert it to another form in preparation for the bottom part of the cycle. During the rise and upper part of the last price cycle Horizen was working hard to maximize the value of the project through many different ways, including spending on research and development, project management, marketing, business development with exchanges and merchants, and working to create adoption in all the countries of the world. During the lower half of the cycle Horizen has reduced the team to the essentials, and worked to build a base of users, relationships with investors, exchanges, and merchants, and continue to develop the higher priority software projects. Lower priority software development, going to trade shows, and paying for business partnerships like exchanges and applications have all been completely stopped. Miners are still a very important part of the Horizen ecosystem, earning 60% of the block reward. 20% goes to node operators, with 20% to the foundation. In the summer of 2018 the consensus algorithm was modified slightly to make it much more difficult for any group of miners to perform a 51% attack on Horizen. This has so far proven effective. The team is strong, we provide monthly updates on a YouTube live stream on the first Wednesday of each month where all questions asked during the stream are addressed, and our marketing team works to develop awareness of Horizen worldwide. New wallet software was released recently, and it is the foundation application for people to use and manage their ZEN going forward. Horizen is a Proof of Work cryptocurrency, and there is no plan to change that by the current development team. If there is a security or centralization concern, there may be change to the algorithm, but that appears unlikely at this time, as the hidden chain mining penalty looks like it is effective in stopping 51% attacks. During 2019 and 2020 the Horizen team plans to release many new software updates:
Sidechains modification to main software
Sidechain Software Development Kit
Governance and Treasury application running on a sidechain
Node tracking and payments running on a sidechain
Conversion from blockchain to a Proof of Work BlockDAG using Equihash mining algorithm

Burstcoin (BURST): A Dark Horse That Could Become A Major Cryptocurrency, The King of Proof of Capacity
https://preview.redd.it/nt1qbc9cq4221.png?width=572&format=png&auto=webp&s=d867a4c98e7ab7e9c37c7dc23cc7fb251a5ecec7 https://cryptoiq.co/burstcoin-burst-a-dark-horse-that-could-become-a-major-cryptocurrency-the-king-of-proof-of-capacity/ Currently the cryptocurrency space is flooded with copycat coins and initial coin offering (ICO) tokens, most of which are moving steadily down the ranks on CoinMarketCap as the bear market of 2018 continues. This bear market is weeding out cryptocurrencies that have little long term potential, and cryptocurrencies that have strong communities and unique technology are rising to the top. Burstcoin (BURST) is one such cryptocurrency that is rising to the top, like cream in a glass of fresh milk. This is because the Burstcoin community is filled with diehard Cypherpunks, and BURST is the king of Proof of Capacity. Back in the middle of October 2018 BURST was at #248 on CoinMarketCap, which was before the ‘nuclear’ bear market took effect, where the support level was broken due to the Bitcoin Cash hard fork, Bakkt delaying the launch of physical Bitcoin futures, and the Securities and Exchange Commission (SEC) initiating its first civil enforcement penalties against ICOs. BURST has decreased in price like every other cryptocurrency, but is rising relative to other cryptocurrencies, and as of 3 December 2018 sits at #199 on CoinMarketCap with a market cap of USD 13.5 million. This increase in the price of BURST relative to other cryptocurrencies is due to Burstcoin’s unique technology. Burstcoin is the king of Proof of Capacity, a mining algorithm that uses the hard drive, versus raw computational power like with Proof of Work, and is much more energy efficient than Proof of Work. Proof of Capacity works by writing cryptographic hashes to an allotted segment of a hard drive called a plot. This plot is then read during mining to find the correct cryptographic hash, and whoever finds the cryptographic hash the fastest receives the block reward. More hard drive space dedicated to the plot equals more cryptographic hashes available, making it easier to find an answer and earn the BURST block reward. Currently 1TB generates 1-2 BURST per day, and even though this is only equivalent to about a penny, it is all profit since reading the plot file requires a negligible amount of energy, and BURST miners can use their computer for other activities without impediment. Compare this to Proof of Work, which slows down personal computers and costs more electricity than the cryptocurrency it mines. BURST is one of the only cryptocurrencies that can be profitably mined on personal computers. Further, unlike with Proof of Work where specialized mining equipment is required like application specific integrated circuits (ASICs), anyone with a computer or even mobile phone can mine BURST, and if they decide to stop mining BURST they can simply delete their plot file and use the hard drive space for other things. This is unlike ASICs, which cannot be used for anything but mining, so if someone decides to stop mining they lose all the money invested into the ASIC. The ease of mining and negligible energy usage has led to the formation of a strong BURST mining community, with over 200,000 TB securing the BURST network. This is equivalent to hundreds of thousands of personal computers. The expansive mining community gives BURST value, and some of these miners are blockchain developers, and they have been building a full suite of technology based on the Burstcoin blockchain. CloudBurst immutably stores files directly on the Burstcoin blockchain, for a small 1-time fee. Real blockchain storage is a rarity in the cryptocurrency world. The file will be stored as long as the Burstcoin blockchain exists, which is the foreseeable future and beyond considering the expansive BURST mining community. Cloudburst would be useful if you lost your computer and all of your backups in a natural disaster like a hurricane, and is a more secure solution than cloud storage like Google. Also, the Burstcoin wallet can be used to easily issue cryptocurrencies that are based off of the Burstcoin blockchain, and there is a decentralized exchange built-in to the wallet to trade these crypto assets. Cryptocurrency scalability is a problem even for major cryptocurrencies like Bitcoin and Ethereum, but Burstcoin has tackled and solved this problem with the launch of the Dymaxion. The scalability of the Dymaxion is so powerful that it can handle all the non-cash transactions in the world. This is done via the utilization of tangle-based lightning networks on top of the Burstcoin blockchain. Transactions done via the Dymaxion are instant, with no fees and practically no energy expenditure. The Dymaxion gives Burstcoin the room to grow as much as it needs to. When people look for the cryptocurrencies that will survive long term, it can be confusing due to the 2,000+ cryptocurrencies listed on CoinMarketCap. However, it is clear that cryptocurrencies with truly unique and useful technology, as well as strong communities will always be around and gain value long term relative to all the ICOs and copycats. Bitcoin is the king of SHA-256, Litecoin is the king of Scrypt, Ethereum is the king of blockchain-based dApps, Dogecoin is the king of the shibes on Reddit, Dash is the King of X11, Monero is the king of privacy coins, IOTA is the king of Directed Acyclic Graphs (DAGs), and Burstcoin is the king of Proof of Capacity. These kings of cryptocurrency will definitely be the winners and survivors when the fallout from the ICO apocalypse is over. This is for educational purposes only and is not investment advice. We are not paid by BURST to write this article.
Alright, I keep seeing you fucks talk about how "Bitcoin is going to make Nvidia/AMD go to the moon". I'm going to walk all you fucks through bitcoin, crypto currencies, and how they effect the GPU market. What is Bitcoin? Bitcoin is a decentralized ledger. That's pretty much it. A set number of bitcoin is generated per block, and each block is solved when a resulting hash is found for the corresponding proof of work. The difficulty is adjusted periodically based on a formula, meaning that as hash rate rises and falls, the number of bitcoins produced per day is roughly the same. What does Bitcoin have to do with AMD and Nvidia? Fucking nothing. Bitcoin is mined on proprietary hardware called Application-specific Integrated Circuits (ASICs). Neither AMD or Nvidia produce these. Why does everyone keep talking about Bitcoin and AMD then? Because they're fucking retarded and you're listening to retards. Bitcoin runs on the SHA-256 Hashing Function which people have custom hardware for. The Crypto driving GPU sales is ETHEREUM, NOT BITCOIN What the fuck is Ethereum then? Don't worry about it. It's for smug assholes who are too edgy for Bitcoin. All you need to know is it runs on a different Hashing function than Bitcoin, so if you weren't a retard you'd probably realize that the proprietary hardware I talked about earlier won't work with it. Currently Ethereum is being mined the same way Bitcoin was when it first started; on GPUs. When are you going to tell me what to buy Shut the fuck up, learn something or kill your self. How many GPUs are being used to mine currently? Currently the Ethereum Hash Rate is 73,000 GH/s. For upcoming earnings, we should instead look at the period from April to June. April 1st shows a network hash rate of 16,500 GH/s, and June 31st shows 59,200 GH/s, meaning the network hash rate increased by 42,700 GH/s for this upcoming earnings report quarter. I've linked a decent benchmark for GPU hashrate . You should notice that all of these are quoted in MH/s, versus the Network reporting in GH/s; there are ALOT of fucking GPUs running on the network. A top of the line 1080 puts out about 20-25 MH/s, a good Radeon card does about 30. As a rough estimate, lets assume that the average card mining Ethereum currently produces about 25 MH/s. 42,700GH/s / 25MH/s means that there are 1.7 MILLION more GPUs currently mining ethereum than there were at the beginning of Q1. Based on my personal observations being involved in this, AMD is actually taking a majority market share of the sold cards just due to their superior performance compared to Nvidia's 1080s, and I'd estimate that About 50-60% of the cards currently mining Ethereum are AMD Radeons. What does this all mean? AMD are selling their highest margin video cards faster than they can produce them, and at ~250$ a pop with 50%-60% market capture AMD will have sold roughly 200-300 million dollars more in video cards than they did last quarter. AMD quarterly revenue last reported was just under 1 Billion. This is a 20-30% increase in revenue from last quarter, where Ethereum Hash Rate only increased by about 10,000GH/s. Even assuming a modest 30% margin for their video cards, AMD will still have almost 60 million in unexpected earnings this quarter due to crypto mining, which translates to about .06-.1 per share in earnings. tl;dr Ethereum will make AMD beat revenue by 20-30%. BUY AMD YOU CUCKS.

Achieving consensus in distributed systems – that chink in the armor hasn't gone away
First a disclosure: My name is Will, I founded Novauri, and our team is building a service that will allow users to buy and sell bitcoin in the US while keeping full control of their private keys as a mandatory design element, not an option. Please SIGN UP for our US only closed beta test in 2015 here. It's super fast, takes 20 seconds, and we'll guarantee no transaction fees for the life of your account. Plus our rates will be highly competitive. Read all about it on the website! I don’t like marketing, I intensely hate the spam I see on the forums, so my approach is going to be to write (semi) intelligent posts and hopefully gain customers through interaction and discourse, as opposed to spamming it up with astroturf and pictures of hipsters having fun that you could be like if you used our product. Now… my thoughts. Proof of work – a tragedy of the commons Not very long ago a mining pool called ghash.io reached 55% bitcoin mining power. It’s widely known that POW suffers from the tragedy of the commons. Mining is SHA256x2, which makes it really simple to build coin flipping application specific integrated circuits (ASICs) that run this faster than general purpose processors. This creates an economic incentive towards centralization where miners who can access the best ASICs first have a major advantage in hashing power per dollar. Pools, a solution to a market demand that exacerbates the problem A second problem is a solution to an economic demand, the existence of mining “pools”. Because a block is solved only every 10 minutes, as bitcoin scales, it becomes increasingly unlikely to ever solve a block by yourself, even with substantial processing power. Mining pools allow the “little guys” to participate too and contribute their hashing power to a pool of miners. This way they receive a portion of any block solved by the pool, enabling a steady and more consistent return on their investment in hardware, facilities and electricity. Yet while pools solve a problem, they create a second issue, the centralization of mining power by pool operators. Because the blocks are “solved” by the managing pool directly, this gives the pool the same controls and ability to act poorly as if they had the hardware themselves. One might argue that market forces will naturally correct things if a mining pool approaches 51%, but this has been disproven in practice with ghash.io. Selfish miners using ghash.io essentially put the entire system in dire peril by letting ghash.io reach 55%. They waited for others to “go first” before switching pools. This is the very definition of “tragedy of the commons”. I would argue it was only the price of bitcoin that changed the miners’ behavior, and reviewing the charts shows that the prices did not lead the mining power concentrations at all, which also defies common wisdom, but in reality is entirely true. P2P pool is a great idea, but it has not offered the same economic benefits to miners as other privately run pools on a balance sheet. Until it does, don't look there for a long term answer. Miners are trying to make a return, and if a pool gives them an advantage, most will use that pool over P2P. Mining is not a charity. Proof of state – lack consensus and bring monopoly issues Some might point to proof of stake as a potential solution (POS). Put very simply, POS is where by virtue of the fact that you own X virtual currency, you have a proportionate chance to win a vote or tiebreaker when confirming transactions. Unfortunately, POS fails to provide a disincentive to fork and suffers from the monopoly problem. Ownership carries voting rights, and there is nothing wasted (no work) by voting for both sides of a fork. There is no consensus, so POS systems are generally hybrid models where POW is used to achieve consensus of forks regardless. POS also has a monopoly problem, which are as serious as POW’s problems. So solving bitcoin's problems with POS seems like a dead end. Very smart people have tried, and so far nothing viable has materialized that is stable enough to be trusted with something as mature and valuable as bitcoin. So… let’s relist all of the bad news!!!
POW suffers from the tragedy of the commons, in that economies of scale right now favor centralization of mining power, yet this same centralization threatens security, which hurts everyone including the centralizing miner. What’s worse are mining pools which serve a valid purpose (normalizing rewards for mining) but compound the issue of centralization.
POS fails because of monopolies and lack of consensus when forks occur.
Solutions thus far are myopic, influenced by personal interests or blimp sized egos (I am one to talk), and are often more academic than pragmatic. Most are just to complicated to work or to be implemented safely without years of refinement in an alt coin. Well, is there hope? What is the practical thing to do? Should we do nothing? I would argue that there are three problems we must solve at once, and all three problems are very much interrelated. It’s one @[email protected]@ of a puzzle. We need to: 1) Make pooled mining uneconomical 2) Figure out a way to make small scale mining cost advantageous 3) Do 1 and 2 but allow normalized returns for little guys so they can run a small business or profitable hobby, without it being a lottery ticket. Some say that a 51% issue would not be the end because we would know very quickly who the bad actor is and could react accordingly. I’m a little more concerned. A real shakeup in the core of bitcoin would shake confidence, and could set us back years. I feel we should as a community put a much higher priority on finding a practical, viable solution. Nothing academic, nothing incredibly complicated, but something that can shift the economics of the situation and solve the three problems listed above. While we have plenty of issues around individual usability, this is, in my humble opinion, the largest remaining vulnerability in bitcoin today. So… what to do? How do we solve all three of these problems at once? What are the possible combinations of solutions that work? Let me take a stab at it… 1) Deterring pooled mining Let’s give more serious consideration to two-phase mining. The idea is to keep (SHA256(SHA256(header))) and add a requirement for (SHA256(SIG(header, privkey))), requiring the block to be signed with the private key of the miner. This kills pooled mining, dead. Miners can solve SHA256x2 but the pool needs the miner’s private key to sign the block header, which would allow the miner to steal the reward, which kills pools very fast. 2) Disincentivizing centralization of mining power 2a) Small scale heat recovery systems We need to get people thinking about small scale heat recovery systems built around mining hardware. This will allow mining activity to serve as a source of heat in cold climates, or perform work where heat is required. One example might be liquid submersion of the asic or heatsinks couples with a pump, radiator and fan in small, modular design might be economically viable. Electric heat is used very commonly, and when powered from clean power sources like solar, geothermal, nuclear (yes, nuclear I would count in the “clean” bucket) and wind, the net is a zero emission system that heats like an electric heater but adds security to the financial system in return, and generates profit for the beneficiary. 2b) Rotating or amorphous block hashing algorithms Another possibility is to rotate or add complexity to the hash algorithms used to solve blocks. Instead of SHA256x2, perhaps SHA256x2 is rotated with scrypt? Perhaps there are many algorithms that rotate to add even more complixity. This would at a minimum make it much harder to design ASICs, and would institute a memory requirement as well. This would at least close the gap between specialized mining operations and home hobbyists. The problem is, what miner in their right mind would go with a hard fork in this direction? This is likely unviable because of economics. 2a is probably the way to go. Is there a 2c or d? 3) Normalizing returns The issue here is that coinbase generation in a decentralized model is like winning the lottery. Your 2a heater would be unlikely to ever solve a block in it’s lifetime. So this last issue is even harder to solve than 2. 3 is the reason mining pools were created in the first place. How do you increase reward frequency while lowering reward to generate a more predictable return? Or maybe we are asking the wrong question or thinking in the wrong direction or dimension? Is there a way to centralize and normalize rewards in a safer way? Could the heater's price be subsidized by the mining activity if that activity was safely hard wired in the heater's hardware to pay block rewards to the reseller or manufacturer? Could electricity rates be offset by rewards going to electricity companies as a subsidy to completely smooth out the return on investment for a bitcoin heater? That last one is tough and would need a really great strategy to reach a critical mass. Does anyone smarter than me have an idea? This is really the problem. It’s three interrelated issues.

Bitcoin (BTC ou XBT) é o primeiro e mais importante dinheiro eletrônico sem autoridade central, baseado numa tecnologia open-source inédita chamada Blockchain, que foi desenvolvida por Satoshi Nakamoto em janeiro de 2009. Essa tecnologia permite a criação de um "banco de dados" confiável P2P (ponto-a-ponto), o que abre caminho para muitos tipos de inovação, sendo uma delas o próprio bitcoin e outras como contratos descentralizados, por exemplo. Nota: normalmente emprega-se "Bitcoin" em maiúsculo para se referir ao protocolo (baseado na tecnologia Blockchain) e em minúsculo "bitcoin" para se referir a uma unidade da moeda. O Bitcoin, além de um bem digital, pode ser considerado também um sistema de pagamento, totalmente independente de qualquer sistema já existente, como cartões de crédito, Paypal, bancos e outros. Sua capacidade atual estimada é de 7 transações por segundo, mas essa capacidade pode ser aumentada com o passar do tempo se houver necessidade. Por ser puramente digital e distribuído, o Bitcoin funciona 24/7 e tem alcance mundial, além de ter locais especializados de troca pela moeda local (chamados exchange) nas principais cidades do mundo. A segurança da rede do Bitcoin, ou seja, o que garante que não existirá um chamado "gasto duplo" do mesmo dinheiro, é o consenso da rede P2P feito pela validação das transações por parte dos mineradores. Para que um minerador consiga incluir um bloco válido na rede, ele precisa utilizar um grande poder computacional. O processo de mineração consiste na realização de cálculos matemáticos para a seleção de quais transações válidas serão incluídas no próximo novo bloco do Blockchain, excluindo aquelas que tiveram uma tentativa de "gasto duplo" naquele período. Cada nó da rede, além dos mineradores, também é capaz de verificar a validade das transações incluídas no bloco. É nesse processo também que aparecem os "bitcoins ainda não descobertos". A distribuição dos bitcoins é feita de forma previsível, tendo uma queda de recompensa pela metade de 4 em 4 anos. Serão encontrados no máximo 21 milhões de unidades da moeda.
Quanto vale um bitcoin?
O preço de mercado de um bitcoin é determinado através da lei da oferta e da procura, portanto estando sujeito a variações de preço por causa de acontecimentos políticos e econômicos (como desvalorização e inflação de moedas estatais, conflitos, maior demanda por Bitcoin etc). Assim como nas moedas estatais, o preço do bitcoin varia e pode ser diferente dependendo do lugar em que for negociado. Se você for comprar dólares no Brasil, você terá que procurar uma casa de câmbio que poderá ter a cotação de R$ 3,00 por dólar, por exemplo. Caso vá a outra casa de câmbio, você poderá notar que o preço poderá ser ligeiramente diferente, além das taxas também variarem. Com o Bitcoin não é diferente. Essa variação entre as exchanges (nome comumente usado para se refererir aos locais de compra e venda de bitcoin) são equilibradas pelo mercado através de operações de arbitragem (comprar num lugar mais barato e vender num mais caro). Para se ter uma ideia do preço médio do bitcoin, você pode dar uma olhada em sites como os que seguem:
Por ser uma moeda ainda muito recente (inventada em jan/2009) e ainda não muito utilizada, seu preço de mercado ainda é muito volátil. Isso faz do bitcoin um investimento de risco atualmente. O preço tende a ficar mais estável ao longo do tempo, quando o mercado puder definir com mais exatidão seu "preço real". As oscilações também tendem a diminuir conforme o seu market cap (quantidade de moedas x preço) aumentar. Hoje (2015) o market cap do bitcoin é de US$ 3 bi, o que pode ser considerado pouco se comparado ao valor de algumas empresas como a Dell (US$ 24 bi) ou ainda de outras commodities como o ouro (US$ 2.600 bi). Para um gráfico da volatidade ao longo do tempo, acesse:
O bitcoin é um bem digital e assim como outros bens, pode ser adquirido de diversas formas:
Oferta de bens ou serviços em troca de bitcoins;
Trocando bitcoins por alguma moeda estatal como o real ou dólar em algum lugar especializado ou mesmo diretamente com alguma pessoa física (P2P).
Minerando bitcoins (processo que atualmente é lucrativo apenas a profissionais, e que será explicado posteriormente).
1. Negociação direta (P2P / pessoa a pessoa)
Uma das maneiras mais baratas de se negociar bitcoins, porque não tem taxas, é comprando diretamente de outras pessoas que já possuem a moeda. As duas partes chegam a um acordo de preço e a troca é feita. Geralmente quem tem menos reputação entrega o bitcoin ou a moeda local primeiro. Por ser uma maneira relativamente arriscada, pois não há um mediador para casos de descumprimento de uma das partes, a reputação de alguém deve ser muito considerada. Exemplo: prefira negociar com alguém do seu círculo de amizades (rede de confiança), alguém que você confie muito como familiares e amigos, ou por uma indicação (amigo de amigo). Se a outra parte tem uma reputação duvidosa, prefira negociar aos poucos (divida os valores em várias partes menores e vá trocando aos poucos). Algumas ferramentas auxiliam nesse processo de reputação e rede de confiança, sendo elas:
A mais tradicional, confiável e mais importante: Bitcoin OTC WoT que mantém um "grafo de confiança" e pode ser acessada através de comandos para um bot de um canal IRC. Se quiser aprender mais, entre na comunidade Bitcoin OTC WoT Brasil para pedir auxílio em português.
LocalBitcoins lista alguns interessados em negociar na sua região.
2. Negociação indireta (com intermediário)
Outra forma de se negociar bitcoins (e essa provavelmente é a maneira mais conveniente, embora não seja a mais barata) é utilizando um intermediário que viabilize a compra e venda de bitcoins entre pessoas interessadas. Esses intermediários são as "corretoras" ou "bolsas" de bitcoins (mais conhecidas por exchanges). Essas corretoras fornecem um serviço de intermediação entre compradores e vendedores de bitcoin, cobrando uma taxa para tal. Por causa disso o bitcoin nas corretoras tem um preço final um pouco mais alto do que se fosse comprar de outras maneiras, mas devido ao altíssimo volume, uma operação pode ser realizada instantaneamente. Além de usar exchanges, você também pode encontrar um intermediário na relação P2P, tornando-a mais segura. Exemplo: um amigo em comum, que pode levar uma comissão previamente combinada para intermediar as duas partes. Você pode conferir uma lista de corretoras no ExchangeWar. Algumas das principais corretoras brasileiras são:
Hoje é virtualmente possível gastar os bitcoins em qualquer lugar, usando algum intermediário para trocá-los imediatamente sob demanda por alguma moeda local, como numa exchange ou com serviços como Neteller, Xapo ou Gyft. Alguns locais porém já aceitam a moeda digital diretamente, como é o caso da Microsoft, Dell e Overstock, além de inúmeras outras ao redor do mundo. Confira uma lista com mais de 100 mil lugares que já aceitam diretamente o bitcoin em SpendBitcoins ou no CoinMap. Segue algumas listas de locais que aceitam bitcoin no Brasil:
Para minerar bitcoins você precisa executar um software em um computador especializado (ASIC) que possa realizar uma grande quantidade de operações matemáticas demandada pelo sistema de consenso P2P do bitcoin. Logo após a criação do Bitcoin em 2009, era possível e rentável minerar bitcoins utilizando o processamento de computadores pessoais (através de simples processadores e placas de vídeo), mas com o tempo essa atividade deixou de ser rentável e tornou-se praticamente impossível para tais máquinas. Isso aconteceu pois o interesse no Bitcoin aumentou muito, trazendo assim mais pessoas para a mineração e impulsionando uma corrida por maior quantidade de processamento. Com o avanço da tecnologia e o aumento do interesse por Bitcoin, mais poder de processamento foi adicionado à rede Bitcoin e isso resultou em um aumento da dificuldade para se encontrar novos Blocos. Essa é uma característica do protocolo Bitcoin: quanto maior o poder de processamento da rede, maior a dificuldade para se minerar bitcoins - ou seja, maior a dificuldade para se descobrir novos Blocos. Um bloco é um arquivo que possui uma identificação (data, hora e informações genéricas) e um registro das transações (movimentação de bitcoins entre endereços) mais recentes. Resumidamente, os mineradores são uma forma de manter a rede Bitcoin segura e operante, algo que demanda muito poder de processamento (o que torna inviável o uso computadores de propósito geral para tal fim) e que, como retribuição por essa tarefa importante, gera uma recompensa em bitcoins pelo trabalho. Todas as transações, ou seja, as movimentações em bitcoins realizadas entre endereços (carteiras), são anônimas pois se caracterizam como uma transferência de fundos de um endereço Bitcoin para outro, que, embora tenham relação indireta com pessoas reais, não possuem uma relação direta. Ou seja, não é possível dizer com absoluta certeza que determinada pessoa é detentora de um endereço a menos que ela diga isso em algum lugar - o que torna o Bitcoin algo pseudônimo, não anônimo (você é anônimo apenas se quiser e tiver conhecimentos para tal). Todas as transações da história da rede Bitcoin são públicas e podem ser conferidas em sites como o Blockchain Info. Então...é impossível minerar hoje em dia num PC comum ou notebook? Sim, mas não é lucrativo. Para isso existem os ASICs (Circuitos Integrados de Aplicação Específica, em inglês Application Specific Integrated Circuits), hardwares específicos para mineração. Há uma lista na Bitcoin Wiki, em inglês, onde estão listados todos os ASICs disponíveis no mercado e também placas gráficas e processadores. É importante notar que embora seja possível minerar bitcoins, não é algo recomendado aos brasileiros, uma vez que o equipamento é caro, importado e possui taxas de importação - além da energia elétrica brasileira, que inviabiliza totalmente o processo. Nota: Em processo de desenvolvimento:Guardando seus bitcoins e Ganhando bitcoins.

What Is Litecoin & Differences Between Litecoin And Bitcoin
What is Litecoin? Litecoin (LTC) is the second largest crypto currency only smaller than Bitcoin. Litecoin is the biggest of the so called altcoins and is similar to but with some distinct differences to Bitcoin (BTC). Litecoin was created by Charlie Lee, a former Google employee who goes by the screen name coblee, and was launched on October 7th 2011. LTC is similar to BTC in that it uses a proof of work blockchain, difficulty adjusts every 2016 blocks, and rewards half about every 4 years. LTC is different to BTC in that the LTC network aims to process blocks every 2.5 minutes compared to BTCs 10 minutes. This allows for faster confirmation times. LTC aims to produce 84 Million LTCs which is roughly 4 times as many coins as BTC will eventually produce. LTC uses an algorithm called Scrypt, and BTC uses SHA-256. Scrypt is roughly 1000 times slower than SHA256 which is why you see LTC mining speeds quoted in KH/s (Thousand hashes per second) vs BTCs MH/s (Million hashes per second). LTC was originally designed so that it could be easily mined on CPUs and be resistant to mining on GPUs. With ASICs (Application Specific Integrated Circuits) having taken over the BTC mining world, a common misconception is that Scrypt is ASIC proof. Scrypt is only ASIC resistant just as it was deigned to be GPU resistant. What this all means is that eventually LTC will be able to be mined with ASICs but the increase in speed is not going to be anywhere near what it was with BTC and SHA-256. This fact means that GPU mining will not be wiped out as it was with BTC. LTC uses addresses very similar to BTC addresses. They are a mix of 33 numbers and letters but always start with a L. LTC is often described LTC as silver to BTCs gold. While some BTC enthusiasts dislike LTC and say it takes something away from BTC, alot of people disagree. LTC being a smaller and younger coin has the ability to change things and test new ideas. BTC has a much larger user base and larger team of developers so it can be harder to come to a consensus on changes with BTC. Litecoin devs have recently been helping develop both LTC and BTC by contributing bug fixes to the BTC-qt devs for inclusion in the Bitcoin-qt client. LTCs native client is the Litecoin-qt application which is very similar to the Bitcoin-qt client. Litecoin-qt is available for Linux, Windows and Mac at the official Litecoin website. If you would like to see a guide on how to setup a Litecoin-qt wallet please see How To Create A Litecoin Wallet. Alot of the same things that exist for BTC exist for LTC. Such as: PaperWallets Litecoin Block Explorer Another Block Explorer Litecoin Wiki Litecoin Gambling Litecoin Dice Litecoin Mining Calculator There are many exchanges that support trading LTC for other crypto currencies as well as USD. Some (but not all) exchanges are listed below. BTC-e OKCoin for China Kraken Bitfinex Crypto-Trade I do not endorse any of these exchanges. I am only listing them for information purposes only. As with anything in the crypto world please do your own research before doing any type of transaction. Some links to the LTC community are: LTC Forums LTC Google+ And of course the LTC subreddit A very popular chart website for LTC (and other coins).
When I decided to write this guide, I was throwing cryptocurrencies around like they were nothing. I was foolish in the fact that I disregarded the exchange fees that are attached with the services that those exchanges provided. I'm in by no means a cryptocurrency genius, and I'm still not extremely seasoned at it, but I've learned enough about cryptocurrencies in the past month that I feel confident to pass on the knowledge I have learned and to help those who are overwhelmed on where to start. So what exactly is a cryptocurrency? According to technopedia (n.d.) a Cryptocurrency is a type of digital currency that is based on cryptography. Cryptocurrency uses cryptography for security, making it difficult to counterfeit. Public and private keys are often used to transfer the currency from one person to another. When mining cryptocurrencies, one important concept needs to be established, and that's hash rate. Hash rate is simply a unit of measurement of processing power. The more your hash rate is, the more profitable mining becomes. This guide uses specific sites and software, chosen by myself, as a great springboard into the cryptocurrency world. These sites and software are extremely flexible, easy to use, and integrate very well together. The mining pools I've chosen are multiple currency pools, designed to consolidate a major of the cryptocurrencies together, and instead of using several mining pools, you use three. These are the things you'll need to get started: MultiMiner Accounts at Coinotron, The Mining Pool Co., and BitMinter Accounts at Cryptsy and Coinbase There are a few different ways to mine for cryptocurrencies, the common of which are using your Central Processing Unit (CPU), Graphics Processing Unit (GPU), and Application Specific Integrated Circuit (ASIC) devices. CPU based mining is not profitable any longer, and will cost you money in the end by increasing electricity costs. GPU based mining is still popular, but losing steam against ASIC based mining. If you choose to use your GPU for mining, AMD/ATI based graphics cards (especially the Radeon HD 79xx series of cards), are the most efficient. If you have an nVidia based graphics card, I'm sorry. You can still mine on nVidia cards, but your hash rates are going to be much slower when compared to their AMD/ATI counterparts. If you chose to use GPU mining, Black Friday or Cyber Monday are you best bets for upgrading your equipment. ASIC based mining is quickly losing value with the changing difficulty on all networks, but it's the most cost effective way to increase your hash rate, and see a positive return on any equipment purchases. If my math is correct, using the methods in this guide, in order for any ASIC device to yield a positive cash flow, you've got to get a device that has at least a 5Gh/s rate (such as the Butterfly Labs Jalapeno). Now for the fun part, explaining how everything in this well greased machine is going to work. Patience plays a big part in the cryptocurrency world, and when I first started, I had none. I was so eager to see the amount of Bitcoin go up, regardless of how much I was getting penalized in fees from trading. So, that's the first step on your journey. PATIENCE. I CANNOT emphasize this enough. Sometimes, you've just got to hurry up and wait, the effects of waiting things out on the cryptocurrency market WILL PAY OFF. Step one of this machine is signing up for all three pools (BitMinter, Coinotron, and Mining Pool Co.). This is so that you can actually get server addresses to plug into MultiMiner, after signing up for these services though, you've still got a ways to go. Step two is sign up for Cryptsy. I chose Cryptsy because of the features they're going to offer at a later time, as well as support for 60 cryptocurrencies (which covers all but one of which we can mine). When your Cryptsy account is setup, you will need to go into the Balances portion of Cryptsy, and find all of the currencies in which you will be mining from the pools. Once Balances are loaded up, you will need to click on the Actions button next to the currency, and click Deposit / Autosell, and then Generate Address. There's a small clipboard near the address it generated, and that will copy the address for pasting in the mining pool websites. You will want to copy, and paste all of them to a text document, along with which currency it belongs to. Not only does this keep you from juggling back and forth trying to figure out things, but it helps for reference and setting up MultiMiner. Once you have those accounts setup, you'll want to sign up for Coinbase. A WORD OF WARNING FOR THOSE WHO ARE PARANOID... Coinbase will want to link to a bank account, this is mandatory if you want to trade your currencies for cash. If you want to trade currencies, just for the sake of trading, then you can skip Coinbase altogether. You can transfer your Bitcoins from Cryptsy straight into Coinbase, and then sell the Bitcoins from Coinbase, and straight into your designated bank account. MultiMiner, oh how amazing you are. For every cryptocurrency available in all pools, you will need to add these coins, along with server addresses, log-ins and passwords. To do so, click on the drop down next to the Settings button, and click Coins. From there, click on Add Coin, and choose each coin from a pool. This will list it in the box to the left, and give you the ability to add information on the right. You can add multiple servers as well, in case the current server you're mining on goes down. After all your coins are setup, you'll need to setup your Strategies. Click the drop down next to Settings, and chose Strategies. Check the Enable Strategies check box, choosing Straight Profitability from the drop down, and checking the Strategy every five minutes (that way you're not losing money by mining something that has dropped in price). This aggressive price checking makes it to where you're always on top with whatever you're mining. Also make sure you have Mine the Single Most Profitable Coin selected. Stick with CoinChoose as your price source (under Settings), as CoinWarz charges for there services beyond a certain point. Click Start, and take a vacation. Reading the charts on Cryptsy can be a little tricky, and scary if you've never saw those types of graphs before. Those graphs are called Candlestick Charts, and are used primarily in the stock market. I won't go in to great detail on this, however, you can find a nice cheat sheet on the subject here. I hope everyone enjoyed the guide, sorry for being punctual and brief, but there isn't anything too elaborate of complicated about searching for cryptocurrencies. I love mining as a hobby, mining's fun, and if there is any money to be made off of mining from my end, great, if not, I had fun mining. While compiling a spreadsheet of the minable currencies in this guide, if everything is set up correctly (and assuming servers aren't down), you should be able to mine the following:
And while Mining Pool Co. offers ASICcoin and Unobtainium, ASICcoin isn't supported in MultiMiner, and Unobtanium isn't supported in Cryptsy. I still mine for Unobtanium in hopes that Cryptsy will include it one day. References Cryptocurrency. (n.d.). In technopedia. Retrieved from http://www.technopedia.com/
