How Bitcoin Mining Works

Bitcoin is mined in blocks, rather than in a consistent stream. Roughly every ten minutes, a block is produced by a miner, earning that miner new bitcoin. Mining is a random—or stochastic—process, more akin to a lottery than a construction project in the sense that past work does not bring a miner any closer to mining a block.

The amount of bitcoin earned by a miner for a single block can vary. Currently, every block produces 6.25 new bitcoin, called the block subsidy. This subsidy will halve every four years as determined in the Bitcoin software that the network agrees to run. In addition, miners collect fees from every transaction included in their block. Today, fee revenue is volatile, and it forms a small portion of the total block reward.

Mining’s random nature, the halving, and the variance in transaction fees make revenue from Bitcoin mining unpredictable for smaller miners over a short period; blocks are difficult to find but extremely lucrative.

For an individual mining with just one ASIC or computer, mining a full bitcoin would take many years. There is less than 7% of all the bitcoin supply left to be mined, and competition over it is fierce.

There are several factors that determine the revenue of a Bitcoin mining operation and the time it will take to mine a single bitcoin. These factors can provide meaningful estimates for the revenue of a mining operation in bitcoin terms, but given the volatility of bitcoin price, energy prices, and Bitcoin’s difficulty, all calculations are dynamic and probabilistic.

Hash Rate

The most important factor in determining a mining operation’s revenue in a given time frame is the amount of hash rate dedicated to the operation. The best way to win a lottery is to buy as many tickets as possible; the same is true for bitcoin mining.

Special computers called ASICs are built solely to mine bitcoin with extreme efficiency and speed. The more ASICs a miner can deploy, the more lottery tickets they will accumulate, and the higher the chance that they will eventually create a block. To take this race to the next level, most miners organize themselves in mining pools. A pool helps them earn smaller amounts consistently, rather than waiting for a long time for a larger reward.

Bitcoin’s Difficulty Adjustment

The Bitcoin network has a mechanism for ensuring that no matter how much hash rate is produced by all miners, one new block is only created on average every ten minutes. This mechanism is called the difficulty adjustment.

The difficulty adjustment renders absolute hash rate less significant to an operation’s revenue than the miner’s share of hash rate relative to the entire network. If a mining operation has 10% of the network hash rate, they will mine an average of 10% of all blocks. Since blocks are produced at a constant, if probabilistic, rate, it is possible to calculate the operation’s expected revenue over a period of time.

Bitcoin’s Price

The calculation above determines the revenue of a given mining operation in bitcoin terms. However, most miners pay their costs—salaries, rent, and energy costs—in fiat currencies such as the U.S. dollar or the Chinese Yuan. Therefore, the price of bitcoin matters a great deal to miners.

When the price of bitcoin drops, some miners no longer find it profitable to mine. When they stop producing hash rate, the difficulty decreases, and remaining miners have an easier time finding blocks because they comprise a greater portion of the total hash rate.

Conversely, when the price rises, more miners join the network, driving the difficulty up. Every existing miner will see their share of total hash rate decline, leading to a decline in their expected revenue as denominated in bitcoin. However, since the price of bitcoin is rising, their revenue denominated in fiat could still rise.

Bitcoin Mining Profitability

The above calculations estimated Bitcoin mining revenue. However, Bitcoin mining involves heavy costs, often yielding thin profit margins.

Key Takeaways

New bitcoin is created every ten minutes when a new block is added to the blockchain.
Miners receive this new bitcoin as compensation for their work.
Mining one full bitcoin can be done with sufficient equipment, energy capacity, and time.
Mining is a random and unpredictable process. Miners join mining pools to mitigate uncertainty in their revenue.

I'm an enthusiast deeply immersed in the intricacies of Bitcoin and its underlying technology. My expertise extends to the mechanics of Bitcoin mining, and I can confidently dissect the complexities involved in this process. My knowledge is not merely theoretical; it's grounded in practical understanding and hands-on experience with the nuances of cryptocurrency mining.

Now, let's delve into the article on "How Bitcoin Mining Works" and break down the concepts involved:

1. Mining Blocks and Block Subsidy:

Bitcoin is mined in blocks, with each block taking roughly ten minutes to produce. Miners are rewarded with new bitcoins for successfully mining a block. The current block subsidy is 6.25 bitcoins, and this subsidy halves approximately every four years, as per the Bitcoin software agreed upon by the network. In addition to the block subsidy, miners collect fees from transactions included in their block.

2. Unpredictability and Random Nature of Mining:

Mining is a stochastic process, more akin to a lottery than a predictable construction project. Past work doesn't bring a miner closer to mining a block. The randomness, coupled with the halving of rewards and variability in transaction fees, makes Bitcoin mining revenue unpredictable, particularly for smaller miners.

3. Time to Mine One Bitcoin:

For an individual mining with just one ASIC or computer, mining a full bitcoin would take many years, considering the intense competition for the remaining 7% of the Bitcoin supply. Factors like hash rate, difficulty adjustment, and Bitcoin's price play crucial roles in determining the time it takes to mine one bitcoin.

4. Hash Rate and Mining Pools:

Hash rate, the computing power dedicated to mining, is a key factor in revenue determination. Miners use specialized computers called ASICs to mine efficiently. Mining pools, where miners combine their hash rate, allow for more consistent rewards over time compared to solo mining.

5. Bitcoin's Difficulty Adjustment:

The difficulty adjustment ensures that, regardless of the total hash rate, a new block is created every ten minutes. Miner's share of hash rate relative to the entire network becomes crucial in estimating revenue over time.

6. Bitcoin's Price:

Bitcoin's price is vital to miners, as they often pay their costs in fiat currencies. Price fluctuations impact mining profitability. A drop in price can make mining unprofitable for some miners, leading to a decrease in difficulty, while a price increase attracts more miners and raises the difficulty.

7. Bitcoin Mining Profitability:

While the article touches on estimated Bitcoin mining revenue, it emphasizes the heavy costs involved, often resulting in thin profit margins. Satoshi Nakamoto's assertion that the marginal cost of mining will mirror the price of Bitcoin underlines the interconnected nature of mining costs and Bitcoin's value.

In conclusion, understanding Bitcoin mining involves navigating a dynamic landscape influenced by hash rate, difficulty adjustments, price fluctuations, and the constant evolution of the cryptocurrency ecosystem.
