How Bitcoin Mining Works

Miranda Marquit has been writing about money for The Balance since Nearly 3, cryptocurrencies are listed on investing. While buying on an exchange like Coinbase is usually fairly simple and allows you to buy fractions of cryptocurrencies, there are those who prefer to mine their coins. The best option likely depends on individual circumstances.

Set up a computer to help solve complex math puzzles and you are rewarded with a coin or a fraction of a coin. The first bitcoin miners were able to earn coins relatively quickly just using what computing power they had in their homes. By , cryptocurrency mining has become a little more complicated and involved. With bitcoin , the reward is halved every four years. You can join a bitcoin mining pool to be more effective, but that comes with a fee, reducing your profits.

Some crypto miners instead opt for other currencies. Some other cryptocurrencies are worth very little in U. On top of building your rig, you also need to realize that you are going to be using quite a lot of power. If you have high power rates, you could end up spending quite a lot to mine coins—especially bitcoin.

A less powerful rig mining alternative currencies could save you money. Even so, it can take several weeks, or even months, to recoup your original investment and become profitable. If you purchase a higher hash rate, you are expected to receive more coins for what you pay for, but it will cost more. Depending on the company you choose, you might pay a monthly fee, or you might pay according to the hash rate.

In general, cloud miners that allow you access to bitcoin come at higher rates. In some cases, you might be required to sign a year-long contract, locking you in. If the value of the cryptocurrency drops, you could be stuck in an unprofitable contract. As it is, depending on what you mine, it can take several months before your cloud mining investment becomes profitable.

Buying bitcoins with hope of their value rising is equally risky. The market for cryptocurrencies is young, and for every analyst who sees great potential, there is another who expects the market to go bust.

Banks such as JP Morgan still view cryptocurrencies as unproven and likely to drop in value. The bottom line is that bitcoin and other cryptocurrencies remain a high-risk, high-reward investment with little consensus about the economic roles they will play in the coming years.

How does bitcoin mining work? The aim of bitcoin—as envisaged by Satoshi Nakamoto, its elusive creator—is to provide a way to exchange tokens of value online without having to rely on centralised intermediaries, such as banks. But if there is no central authority, who decides which transactions are valid and should be added to the blockchain? And how is it possible to ensure that the system cannot be gamed, for example by spending the same bitcoin twice? The answer is mining. The first miner to find the solution announces it to others on the network. The other miners then check whether the sender of the funds has the right to spend the money, and whether the solution to the puzzle is correct.
