Best mining rigs and mining PCs for Bitcoin, Ethereum and more

Bitcoin mining is the process by which new bitcoins are entered into circulation. It is also the way the network confirms new transactions and is a critical component of the blockchain ledger's maintenance and development. The first computer to find the solution to the problem receives the next block of bitcoins and the process begins again.

Cryptocurrency mining is painstaking, costly, and only sporadically rewarding. Nonetheless, mining has a magnetic appeal for many investors who are interested in cryptocurrency because of the fact that miners receive rewards for their work with crypto tokens.

This may be because entrepreneurial types see mining as pennies from heaven, like California gold prospectors in And if you are technologically inclined, why not do it? The bitcoin reward that miners receive is an incentive that motivates people to assist in the primary purpose of mining: to legitimize and monitor Bitcoin transactions, ensuring their validity.

Because many users all over the world share these responsibilities, Bitcoin is a "decentralized" cryptocurrency, or one that does not rely on any central authority like a central bank or government to oversee its regulation. However, before you invest the time and equipment, read this explainer to see whether mining is really for you. Throughout, we use "Bitcoin" with a capital "B" when referring to the network or the cryptocurrency as a concept, and "bitcoin" with a small "b" when we're referring to a quantity of individual tokens.

Blockchain "mining" is a metaphor for the computational work that nodes in the network undertake in hopes of earning new tokens. In reality, miners are essentially getting paid for their work as auditors. They are doing the work of verifying the legitimacy of Bitcoin transactions.

This convention is meant to keep Bitcoin users honest and was conceived by Bitcoin's founder, Satoshi Nakamoto. By verifying transactions, miners are helping to prevent the " double-spending problem.

Double spending is a scenario in which a Bitcoin owner illicitly spends the same bitcoin twice. Though counterfeit cash is possible, it is not exactly the same as literally spending the same dollar twice. With digital currency, however, as the Investopedia dictionary explains, "there is a risk that the holder could make a copy of the digital token and send it to a merchant or another party while retaining the original.

If you were to try to spend both the real bill and the fake one, someone who took the trouble of looking at both of the bills' serial numbers would see that they were the same number, and thus one of them had to be false. What a blockchain miner does is analogous to that—they check transactions to make sure that users have not illegitimately tried to spend the same bitcoin twice. This isn't a perfect analogy—we'll explain in more detail below.

Only 1 megabyte of transaction data can fit into a single bitcoin block. The 1MB limit was set by Satoshi Nakamoto, and this has become a matter of controversy because some miners believe the block size should increase to accommodate more data, which would effectively mean that the Bitcoin network could process and verify transactions more quickly. In addition to lining the pockets of miners and supporting the Bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation.

In other words, miners are basically "minting" currency. For example, as of January , there were just under 19 million bitcoins in circulation, out of an ultimate total of 21 million. Aside from the coins minted via the genesis block the very first block, which founder Satoshi Nakamoto created , every single one of those bitcoins came into being because of miners.

In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin. However, because the rate of bitcoin "mined" is reduced over time, the final bitcoin won't be circulated until around the year This does not mean that transactions will cease to be verified.

Miners will continue to verify transactions and will be paid fees for doing so in order to keep the integrity of Bitcoin's network. To earn new bitcoins, you need to be the first miner to arrive at the right answer, or closest answer, to a numeric problem.

This process is also known as proof of work PoW. To begin mining is to start engaging in this proof-of-work activity to find the answer to the puzzle. No advanced math or computation is really involved. You may have heard that miners are solving difficult mathematical problems—that's true but not because the math itself is hard. What they're actually doing is trying to be the first miner to come up with a digit hexadecimal number a " hash " that is less than or equal to the target hash.

It's basically guesswork. So it is a matter of randomness, but with the total number of possible guesses for each of these problems numbering in the trillions, it's incredibly arduous work. And the number of possible solutions referred to as the level of mining difficulty only increases with each miner that joins the mining network. In order to solve a problem first, miners need a lot of computing power. Aside from the short-term payoff of newly minted bitcoins, being a coin miner can also give you "voting" power when changes are proposed in the Bitcoin network protocol.

In other words, miners have some degree of influence on the decision-making process for matters such as forking. The more hash power you possess, the more votes you have to cast for such initiatives. The rewards for Bitcoin mining are reduced by half roughly every four years.

When bitcoin was first mined in , mining one block would earn you 50 BTC. In , this was halved to 25 BTC. By , this was halved again to On May 11, , the reward halved again to 6.

As of Jan. Not a bad incentive to solve that complex hash problem detailed above, it might seem. To keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock , which updates this information in real time. Interestingly, the market price of Bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation.

This lowering inflation rate increased scarcity and, historically, the price has risen with it. If you want to estimate how much bitcoin you could mine with your mining rig's hash rate, the site CryptoCompare offers a helpful calculator. Other web resources offer similar tools. Although individuals were able to compete for blocks with a regular at-home personal computer early on in Bitcoin's history, this is no longer the case.

The reason for this is that the difficulty of mining Bitcoin changes over time. In order to ensure the blockchain functions smoothly and can process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are 1 million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem.

For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks.

When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate.

Less computing power means the difficulty level decreases. At today's network size, a personal computer mining for bitcoin will almost certainly find nothing. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a graphics processing unit GPU or, more realistically, an application-specific integrated circuit ASIC. Some miners—particularly Ethereum miners—buy individual graphics cards as a low-cost way to cobble together mining operations.

Today, Bitcoin mining hardware is almost entirely made up of ASIC machines, which in this case, specifically do one thing and one thing only: Mine for bitcoins. Today's ASICs are many orders of magnitude more powerful than CPUs or GPUs and gain both more hashing power and energy efficiency every few months as new chips are developed and deployed. Say I tell three friends that I'm thinking of a number between one and , and I write that number on a piece of paper and seal it in an envelope.

My friends don't have to guess the exact number; they just have to be the first person to guess any number that is less than or equal to it. And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the "guess what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners, and I'm thinking of a digit hexadecimal number.

Now you see that it's going to be extremely hard to guess the right answer. If B and C both answer simultaneously, then the system breaks down. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions. The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but haven't verified the most transactions are not rewarded with bitcoin.

Here is an example of such a number:. The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal. The decimal system uses factors of as its base e. This, in turn, means that every digit of a multi-digit number has possibilities, zero through In computing, the decimal system is simplified to base 10, or zero through nine.

In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine.

If you are mining Bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash. Remember that analogy, in which the number 19 was written on a piece of paper and put in a sealed envelope? In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash.

What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many " nonces " as possible, as quickly as possible.

The Surprising Relationship Between Cryptocurrency and Gold

Cryptocurrencies fought to find a foothold on Monday after cheerleading from Tesla boss Elon Musk at the weekend seemed unable to offset pressure from spooked investors amid a crackdown on the asset class in China. Musk had lent a bid on Saturday by tweeting support for crypto in "the true battle" with fiat currencies. But on Sunday, prices slumped as "miners" - those who mint crypto by verifying transactions - halted Chinese operations in the face of increasing scrutiny from authorities. The trigger for the initial crypto selloff appeared to come from a hardening stance from Chinese regulators last week, which stepped up further on Friday when a State Council committee in the country vowed to crack down on miners in particular. Late on Sunday, Huobi Mall, part of cryptocurrency exchange Huobi, said on Monday it suspended crypto mining that services mainland Chinese clients. TOP, a crypto mining pool, has suspended its China business citing regulatory risks, while crypto miner HashCow said it would halt buying new Bitcoin "rigs".

Fidelity CEO Abigail Johnson says the company is mining cryptocurrencies

An obstacle to large-scale bitcoin mining is finding enough cheap energy to run the huge, power-gobbling computer arrays that create and transact cryptocurrency. One mining operation in central New York came up with a novel solution that has alarmed environmentalists. It uses its own power plant. The megawatts dedicated to Bitcoin might be enough electricity to power more than 35, homes. Proponents call it a competitive way to mine increasingly popular cryptocurrencies, without putting a drain on the existing power grid. Environmentalists see the plant as a climate threat. They fear a wave of resurrected fossil-fuel plants pumping out greenhouse gasses more for private profit than public good. The former coal plant, in a touristy region known for its glacial lakes and riesling wines, was converted to natural gas by Greenidge and began producing electricity in

Interest in cryptocurrency, a form of digital currency, is growing steadily in Africa. Some economists say it is a disruptive innovation that will blossom on the continent. Cryptocurrency is not bound by geography because it is internet based; its transactions are stored in a database called blockchain, which is a group of connected computers that record transactions in a ledger in real time. Created in by a person or people with the alias Satoshi Nakamoto, investors hope Bitcoin becomes the new mode of financial transaction in the digital age.

The province courted crypto miners with affordable energy. Will they stick around when the digital gold rush ends? Saint-Hyacinth, one of several small Quebec cities with a Bitfarms mining facility Guillaume Simoneau. In places like Saint-Hyacinthe, Quebec, in the bowels of long-abandoned warehouses, there is the sound of money being made. This literal wall of sound is looped with wires and pulsing with green lights—some near-future set piece plunked into the industrial scrapes of a Montreal exurb. The noise and heat—the room feels like a Florida tarmac—is the by-product of 6, computers. Each one is roughly the size of a loaf of bread and is doing the same thing as its many neighbours: cracking mathematical equations. It then moves on to another equation.
