Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to . Mining. Bitcoin mining is the process of making computer hardware do mathematical calculations for the Bitcoin network to confirm transactions and increase security. As a reward for their services, Bitcoin miners can collect transaction fees for the transactions they confirm, along with newly created bitcoins. The Bitcoin network compensates Bitcoin miners for their effort by releasing bitcoin to those who contribute the needed computational power. This comes in the form of both newly issued bitcoins and from the transaction fees included in the transactions validated when mining bitcoins.

We have tried to calculate the amount of money that the Chinese have invested in mining, we estimate it to be in the hundreds of millions of dollars. Even with free electricity we cannot see how they will ever get this money back. The same Chinese competitive advantage has been doubly effective at squeezing the profit-dependent hobbyist miner from the market. With the block reward halving looming, the profitability of all but the most efficient operations will likely be challenged.
Given that profits derived from the current generation of mining hardware are dwindling and will likely reach negative returns post-halving:. Can the new S9 change the game for smaller and hobby miners and restore their lost profitability?
Note: Before you buy an Antminer S9 make sure you already have Bitcoin mining software and a Bitcoin mining pool. The first batch of S9s will be available for order directly from Bitmain from the 12 th of June. However, the lower your electricity costs, the better your odds of the miner paying for itself within a reasonable timeframe. Judging value in this space is a complicated exercise, although it would appear that nothing vastly technologically-superior to the S9 is likely to be released in the near future.
The release cycle of a new generation of mining hardware every few months is likely to decelerate from this point on, as manufacturers have transitioned to cutting-edge 16 and 14nm designs. The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology. The 16 nm fabrication process used in the manufacture of the S9 is a major improvement upon the 28 nm design common to other modern mining devices.
Although a 10nm process is on the horizon for , further increases beyond that remain theoretical. Further, the design and manufacture of any 10nm Bitcoin mining hardware is likely to take at least a year. Our guide on the best bitcoin wallets will help you get one fast and for free.
Read it here! The good news is that existing power supplies, at least those of sufficient wattage, are fully compatible with the S9. A total of chips, spread over 3 circuit boards, are combined to achieve this phenomenal hashrate. Note that Power Cost will be specific to your location and that Difficulty changes every 2 weeks, usually to the upside…. Your Pool Fees will be determined by your mining pool; although the S9 is plenty powerful, a single unit is highly unlikely to find any blocks when solo-mining.
Of course, such impressive results assume all factors stay constant which is hugely improbable in the ever-changing world of Bitcoin! The cutting-edge manufacturing process is what makes the S9 the most electrically-efficient mining device to date.
It uses a mere 0. The S9 consumes about W more than the S7. Apart from the power supply, the S9 is a self-contained unit.
It requires no connection to another computer to interface with other Bitcoin nodes. The S9 performs reliably in any well-ventilated space, whether a single or several unit s kept in a spare room or hundreds to thousands of units in a large mining center. On the other hand, the halving could bring about a higher Bitcoin price and reduced competition, increasing profitability. It is likely to remain profitable for far longer than previous generations of ASIC miner, although ROI cannot be guaranteed given the inherent unpredictability of Bitcoin mining.
Bitmain is regarded as one of the most influential companies in the ASIC mining industry. Halong Mining is no longer around. It seems they could not compete with the already established ASIC manufacturers, most likely because they could never fill their orders and get the partsd they needed to produce enough miners to make money. The DragonMint W power supply is strongly recommended, though not mandatory. Each miner requires its own individual power supply.
Professional mining hardware runs optimally at V, hence why mining farms step down their own electricity supply to V. In any case, it would be a good idea to buy the DragonMint power supply.
These PSUs will get the job done, but they are not ideal for optimum mining performance. Consuming merely 0. Keep in mind that exact power consumptions vary, especially depending on which power supply you are using. Take a look at the projected mining profitability of a single miner :. The Antminer R4 hashes at up to 8. BitFury was the first company to release 16nm chips. As the saying goes nothing good comes cheap. With all the awesome features that come with the Antminer R4 you would expect its price to be high.
Its price is among its cons because this may be too high for the average hobby miner. Once you setup your Antminer R4 you will see that its user interface has been well designed with the users in mind.
All you have to do is enter your wallet address and mining pool settings before you start mining. It is also possible for you to customize settings such as the fan speed or the frequency.
With a hash rate of 8. Rest easy because most homes have an outlet that can handle Watts safely but also expect your electricity bills to rise significantly. Of course we assume that all factors remain constant which is almost impossible in the ever-changing world of Bitcoin. This means that the Antminer R4 will eventually produce a profit, but only if the network hash rate, Bitcoin price, and electricity costs stay the same.
All of those factors are a big IF, since the network difficulty almost always increases. So you are definitely taking on risk with this miner, and it may not be worth your time despite the many benefits it provides over other hardware. One of the most unique features of Antminer R4 is that it was designed to ensure the least possible sound with the maximum hash rate.
Antminer R4 replaces the traditional fan with a rotary blade system. The traditional fan has been the biggest source of noise for other mining hardware. Its fan speed is controlled automatically, ensuring that the noise is regulated. Bitmain recommends the use of an APW5 power supply.
It also uses 28nm Xilinx programmable logic. It supports Gigabit Ethernet to ensure that mined blocks are submitted instantly. Not only are the devices expensive but they also generate a lot of heat and noise, not to mention the amount of electricity they consume.
Some of these problems mentioned above have been addressed and as a miner you can do it as a hobby while also making some money. This home Bitcoin miner is not only a good fit for hobby miners but also helps to improve the decentralization of Bitcoin mining as a whole.

Profitability Factors The Bitcoin price and the total network hash rate are the two main factors that will affect your profitability. The Bitcoin Price Bitcoin mining is a booming industry , but the Bitcoin price increasing can help make up some of these losses.
Bitmain Antminer S7 Review. Antminer S9 Review. Get a Wallet You can't mine bitcoins with an Antminer S9 without a wallet. This is because Bitcoin's price has remained steady for most of Satoshi designed Bitcoin such that the block reward, which miners automatically receive for solving a block, is halved every , blocks or roughly 4 years.
To successfully attack the Bitcoin network by creating blocks with a falsified transaction record, a dishonest miner would require the majority of mining power so as to maintain the longest chain.
Pools and specialized hardware has unfortunately led to a centralization trend in Bitcoin mining. Bitcoin mining is certainly not perfect but possible improvements are always being suggested and considered. Green sends 1 bitcoin to Red. A full node is a special, transaction-relaying wallet which maintains a current copy of the entire blockchain.
If there are no conflicts e. At this point, the transaction has not yet entered the Blockchain. Red would be taking a big risk by sending any goods to Green before the transaction is confirmed. So how do transactions get confirmed? This is where Miners enter the picture. Miners, like full nodes, maintain a complete copy of the blockchain and monitor the network for newly-announced transactions. In either case, a miner then performs work in an attempt to fit all new, valid transactions into the current block.
Acceptable blocks include a solution to a Proof of Work computational problem, known as a hash. The more computing power a miner controls, the higher their hashrate and the greater their odds of solving the current block. But why do miners invest in expensive computing hardware and race each other to solve blocks?
And what is a hash? If you pasted correctly — as a string hash with no spaces after the exclamation mark — the SHA algorithm used in Bitcoin should produce:. So, a hash is a way to verify any amount of data is accurate. To solve a block, miners modify non-transaction data in the current block such that their hash result begins with a certain number according to the current Difficulty , covered below of zeroes.
If other full nodes agree the block is valid, the new block is added to the blockchain and the entire process begins afresh. Red may now consider sending the goods to Green. You may have heard that Bitcoin transactions are irreversible, so why is it advised to await several confirmations? The answer is somewhat complex and requires a solid understanding of the above mining process:. There are now two competing versions of the blockchain!
Which blockchain prevails? Quite simply, the longest valid chain becomes the official version of events. A loses his mining reward and fees, which only exist on the invalidated A -chain. The more confirmations have passed, the safer a transaction is considered.
This is why what is known as '0-conf' or "0 confirmations" on the Bitcoin Cash blockchain is so dangerous. A company can claim to be a cloud mining company without any proof of actually owning any hardware. Note: If you do find a legitimate one, you'll need a wallet to receive payouts to. A secure hardware wallet like the Ledger Nano X is a good option. It depends what your goals are with cloud mining. If your goal is to obtain bitcoins, then there is really no reason to cloud mine or even mine at all.
If you find a legitimate cloud mining operation and you are making profit, you will very likely need to pay taxes on that profit.
The best way to determine the taxes you owe is to use a crypto tax software. The reason there are so many cloud mining scams is because it is very easy for anyone in the world to setup a website. The company can act legit by sending initial payments to its customers. But after that it can just keep the already received payments for hash power and then make no further payments.
Two of the most famous cloud mining companies have already been exposed as scams: HashOcean and Bitcoin Cloud Services. Even as recently as September of , cloud mining scams are stealing people's money.
The SEC equivalent of the Phillipines just issued a warning to customers of Mining City to get out now and have told promoters of the company that they could go to jail for up to 21 years if they don't stop immedietely. Cloud mining scams are not a thing of the past. They very much so still happen today, so be vigilant or, better yet, just avoid them.
If you beleive you have found a legitimate clound mining company, you can really make sure by putting it to the test. NOTE: the following are taken largely from Puppet's Cloud Mining reddit post, which is a great supplement to this post. If you have purchased options for the right to some amount of hashing power, there is no reason why you shouldn't be able to direct that hashing power to any pool that you want. There are only a handful of ASIC manufacturers who could service a large scale mining operation with hardware.
Any cloud mining operation would not only allow an ASIC manufacturer to disclose a large ASIC purchase, but they'd also want them to do so to prove they are serious. So far, no cloud mining operation we are aware of has has an ASIC manufacturer acknowledge they are selling hardware to a cloud mining company.
Bitcoin mining is very competitive and has incredibly thin margins. There would be no way to mine profitably if they were paying not only you, but also the person who referred you. If there is no way to the know idenntity of the cloud mining operation, there is no way to hold them accountable if they run with the money. It also makes it harder to catch the person who stole your money. WARNING: Just because a cloud mining website boasts a famous person as an investor or advisor does not mean that person is actually investing or advising.
Anyone can throw up a picture of Elon Musk on their site. The real proof is if Elon Musk himself says in a news clip that he is a founder. Investments should never be a one-way transaction.
If you can easily give the cloud miner money, but there is no obvious way to sell your position and get it back, then that is a good indication you will never get your money back.
Any investment that guarantees profits is a scam. If the cloud miner has so far made good on delivering its guarantees, it is because they are using funds from new investors to pay off old ones and appear solvent. Ponzi schemes work this way.
Eventually, they are going to run with the money, but you never know when it will happen. The other point to consider is: if a miner could guarantee profits, why would they sell that right to you? Why wouldn't they take teh guaranteed profits for themselves?
If the amount of shares for sale in the cloud mining operation appear infinite, then they are definitely running a scam. No miner has an unlimited amount of hashing power. Most cloud mining companies accept Bitcoin, PayPal, and credit cards. If a cloud mining company accepts bitcoins then there is a good chance it is a scam. This is because Bitcoin payments cannot be reversed. Once the scam company receives your bitcoin payment you have no way to get your coins back.
Any company offering free trials, especially if they require payment information, is most likely a scam. Our guide on the best bitcoin wallets will help you pick one. Read it here! Cloud mining means a host company owns Bitcoin mining hardware and runs it at a professional mining facility.
You pay the company and rent out some of the hardware. Based on the amount of hash power you rent, you will earn a share of payments from the cloud mining company for any revenue generated by the hash power you purchased. In most cases, though, there is no mining facility or hardware.
There is just a guy taking your money and paying part of it to someone who signed up before you did. Eventually he runs away with the money, and you are left with nothing. Mining software is something you download on your computer. It is required when you OWN mining hardware. Software connects your hardware to the internet so that it can make hashes and communicate with the network. Just find an exchange in your country and buy some bitcoins.
If you're still a bit confused about what Bitcoin mining is, that's okay. That's one reason I built this site, to make it easier to understand! One common question people ask is if they can just invest in the mining companies instead of trying to mine themselves.
The answer is: yes, you absolutely can. And you wouldn't be the only ones investing in these companies. Fidelity, Vanguard, and Charles Schwab Funds have all been buying these stocks en masse. So when Jamie Dimon, CEO of Chase, denigrates Bitcoin , just remember that many of his friends at the big banks are loading up on these stocks themselves.

Well, it's much, much more than that! If you want the full explanation on Bitcoin mining, keep reading Jordan Tuwiner Last updated December 1, Chapter 1 What is Bitcoin Mining? Bitcoin mining is the backbone of the Bitcoin network.
Miners provide security and confirm Bitcoin transactions. Without Bitcoin miners, the network would be attacked and dysfunctional. Bitcoin mining is done by specialized computers. The role of miners is to secure the network and to process every Bitcoin transaction.
For this service, miners are rewarded with newly-created Bitcoins and transaction fees. What is Bitcoin mining actually doing? Miners are securing the network and confirming Bitcoin transactions.
Miners are paid rewards for their service every 10 minutes in the form of new bitcoins. What is Bitcoin Mining Actually Doing?
What is the point of Bitcoin mining? This is something we're asked everyday! There are many aspects and functions of Bitcoin mining and we'll go over them here. They are: Issuance of new bitcoins Confirming transactions Security Mining Is Used to Issue new Bitcoins Traditional currencies--like the dollar or euro--are issued by central banks.
Bitcoin is different. With Bitcoin, miners are rewarded new bitcoins every 10 minutes. Miners Confirm Transactions Miners include transactions sent on the Bitcoin network in their blocks. A transaction can only be considered secure and complete once it is included in a block. More confirmations are better for larger payments. Here is a visual so you have a better idea: 0 Payments with 0 confirmations can still be reversed!
Wait for at least one. Most exchanges require 3 confirmations for deposits. Six is standard for most transactions to be considered secure. Chapter 3 How to Mine Bitcoins. Actually want to try mining bitcoins? Most Bitcoin mining is done in large warehouses where there is cheap electricity.
To be real: Most people should NOT mine bitcoins today. Most Bitcoin mining is specialized and the warehouses look something like this: Source ieee. Step 1: Get Bitcoin Wallet When earning bitcoins from mining, they go directly into a Bitcoin wallet. You can't mine without a wallet. Popular Exchanges. Coinbase High liquidity and buying limits Easy way for newcomers to get bitcoins "Instant Buy" option available with debit card.
