Bitcoin Mining Definition

Since miners use a large amount of electricity, you want to buy one that converts the most amount of electricity into bitcoins. Price — How much does the bitcoin miner cost? Cheap mining hardware will mine less bitcoins, which is why efficiency and electricity usage are important. The fastest and more efficient mining hardware is going to cost more. The best ASIC miner is the most efficient bitcoin miner. Aim for value. Other bundled equipment may be included with your purchase depending on the seller.

You can use a bitcoin mining profitability calculator to determine your estimated cost of return on your mining hardware.

Be sure to take electricity costs into account. Most mining hardware appears profitable until electricity costs are accounted for. The best way to determine actual profitability is to figure out your electricity cost per hash.

That is really what will make or break your operation. Good Bitcoin mining hardware needs to have a high hash rate. But, efficiency is just as important. To improve your efficiency, there are also companies that will let you order hardware to their warehouse and run the miners for you. You could also cloud mine bitcoins.

But both options are a lot less fun than running your hardware! Halong Mining — Halong Mining is the newest mining hardware company. They have the best miner available. Unfortunately, they already sold out of their first batch but a new batch should be available for sale soon. Bitmain — Bitmain makes the Antminer line of Bitcoin miners. Bitmain is based in China and also operates a mining pool.

BitFury — BitFury is one of the largest producers of Bitcoin mining hardware and chips. Its hardware is not available for purchase. Power Supply — Bitcoin rigs need special power supplies to funnel and use electricity efficiently. Cooling Fans — Bitcoin hardware can easily overheat and stop working. Buy a sufficient amount of cooling fans to keep your hardware working.

Backup generators — You may want generators as a backup in case your main source of electricity goes down. You can find Bitcoin mining equipment for sale on eBay. Bitcoin is based on blockchain technology, a decentralized platform which takes power away from a central authority and gives it to the average person.

Sensitive information is stored on the blockchain rather than large data centers, and is cryptographically secured. A vast amount of people, known as miners, all work together to validate the network, instead of just one person or government.

In the beginning, CPU s were used to solve cryptographic hash functions , until miners discovered that GPU s were far better equipped for mining.

As block difficulty increased, miners turned primarily to GPUs. Their hashrates are significantly higher than anything GPUs are capable of.

With stellar performance comes a high price tag — the best ASIC chips will run you a few thousand dollars each. Upon creation, Bitcoin blocks were confirmed by the average person using their desktop — once ASICs hit the market, things changed. ASIC developers, including Bitmain, granted early access to large mining cartels rather than the average person.

Nowadays, a large majority of Bitcoin mining takes place in China where electricity is cheap. Thousands of ASICs all mine simultaneously in a mining farm large warehouse.

Unfortunately, Bitcoin is no longer as decentralized as it was once intended to be. Buy Antminer S7 on eBay. The S7 is also a popular choice among hobbyist miners for its reasonable price and strong performance.

The strong metal casing features a tongue and groove system which allows for the neat arrangement of multiple miners. The APW3 requires a minimum Volts to function and does not ship with the necessary 16A power cord.

While an integral PSU makes for a compact and convenient miner, there are few other reasons to recommend such a setup. The S7-LN also excludes a cord. Note: Before you buy an Antminer S7 make sure you already have Bitcoin mining software and a Bitcoin mining pool.

These prices can be expected to fall further as the S9 and other superior mining hardware becomes the new standard. With careful tweaking, it may be possible to profit from an S7 even at 15c power. The same calculations adjusted for the Hash Rate and Power consumption of the S7-LN produces slightly more encouraging results:.

Naturally, the hotter the environment, the more energy the fan s will consume to cool the unit. The S7 is twice as efficient as the S5 at converting all this energy into bitcoins; it requires a modest 0. Setting them up via the MinerLink GUI is a simple process, requiring only your mining pool credentials to begin mining.

The units will automatically begin hashing upon powering up, which can be helpful in the event of power failure. S7 connectivity is via Ethernet only. They are both cooled by dual fans. A dry basement is an ideal location. This peak was reached on May 24 th Such tremendous growth has been spurred by major investment into Bitcoin mining technology and operations. Profits have accumulated where mining is most profitable China , with the result that several competing operations eg.

KNC have been forced out of the industry. 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.

Because total hashing power or Net Hash is constantly changing, the difficulty of finding a block needs to adjust proportional to the amount of total hashing power on the network. In very simple terms, if you have four miners on the network, all with equal hashing power, and two stop mining, blocks would happen ever 20 minutes instead of every ten.

Therefore, the difficulty of finding blocks also needs to cut in half, so that blocks can continue to be found every 10 minutes. Difficulty adjustments happen every 2, blocks.

This should mean that if a new block is added every 10 minutes, then a difficulty adjustment would occur every two weeks. The 10 minute block rule is just a goal though. Some blocks are added after more than 10 minutes. Some are added after less. Its a law of averages and a lot if left up to chance. That doesn't mean that for the most part, blocks are added reliably every 10 minutes. A measurement of energy consumption per hour.

Most ASIC miners will tell you how much energy they consume using this metric. As Bitcoin could easily replace PayPal, credit card companies, banks and the bureaucrats who regulate them all, it begs the question:. If only 21 million Bitcoins will ever be created, why has the issuance of Bitcoin not accelerated with the rising power of mining hardware?

Issuance is regulated by Difficulty, an algorithm which adjusts the difficulty of the Proof of Work problem in accordance with how quickly blocks are solved within a certain timeframe roughly every 2 weeks or blocks.

Difficulty rises and falls with deployed hashing power to keep the average time between blocks at around 10 minutes. For most of Bitcoin's history, the average block time has been about 9. Because the price is always rising, mining power does come onto the network at a fast speed which creates faster blocks.

However, for most of the block time has been around 10 minutes. 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.
