Understanding Bitcoin mining revenue

Bitcoin miners’ rewards can vary greatly and unexpectedly due to several factors, which is why it’s vital to understand how mining revenue works.

Bitcoin mining revenue is fundamental to keep miner incentives to provide security high.

The basics of Bitcoin mining

Let’s start from the beginning: Bitcoin mining is the process through which all transactions on Bitcoin are confirmed and permanently recorded on the blockchain. In other words, it is how miners provide security and ensure the correct functioning of the network.

This method runs on a consensus algorithm known as proof-of-work, in which miners have to spend a considerable amount of computational power to solve these mathematical puzzles.

As hashrate grows, mining has to become harder to maintain security. Making mining more demanding greatly increases the costs of trying to attack the network.

Thus, Bitcoin automatically adjusts the mining difficulty every 2,016 blocks —approximately two weeks— proportionally to the total amount of hashrate currently working on the network. The more miners there are, the harder it is to find a block.

Mining difficulty is one of the critical factors to determine miners’ revenue. Logically, the harder it is to mine a block, the less profitable mining becomes —you would have to spend more electricity to find a block.

Breaking down Bitcoin mining revenue

Aside from mining difficulty, Bitcoin’s architecture has two other aspects that determine the revenue a miner earns.

Each time a miner finds a new block, they receive a block subsidy and transaction fees. To keep it simple, we will explain this topic without considering the mining pool dimension. We will address that later in the article.

Block subsidies

The first factor to consider is the block subsidy. This is a fixed amount of BTC a miner receives for solving a block. More importantly, it’s also the “new” coins that come into circulation with each block.

An important detail to remember about block subsidies is the event we know as “halving.” Halvings happen every 210,000 blocks —roughly four years— and reduce the Bitcoin issuance by half. This is how Bitcoin controls inflation.

Transaction fees

The other determining factor for mining revenue is transaction fees. Every transaction broadcasted to the Bitcoin blockchain includes a miner fee.

Initially, Satoshi Nakamoto implemented transaction fees to prevent spam transactions that could slow down and clog the network. However, they are also a monetary incentive for miners.

When a miner finds a block, they earn the sum of all the transaction fees included in that block —aside from the block subsidy. That said, users can set specific fee amounts to prioritize their transactions.

Miners don’t confirm transactions in order of arrival. Instead, they choose those with the highest fees for better profits.

Thus, if users need their transactions confirmed immediately, they can choose to pay a higher fee to incentivize the miners to confirm their transactions first.

Bitcoin mining revenue is determined by the block subsidy and transaction fees.

To sum up, miner revenue includes both these elements:

  • The block subsidy, which is a fixed amount of BTC determined by the network.
  • The sum of the fees of all the transactions included in that block.

Together, these two amounts constitute the total earnings for finding a block, known as block reward.

Bitcoin mining revenue and the pool factor

A cryptocurrency mining pool is a group of miners who join their hashpower to enhance their chances of successfully solving a block. By combining and focusing their total computing power, miners can work faster and bump up their hashrate by performing more “guesses” per second.

Essentially, mining pools reduce the miners’ variance, paying miners for finding hashes at a lower difficulty rate. Thus, miners earn more often than if they were mining solo.

Another aspect of mining pools that affects revenue is their payment method and fees. Not all pools reward miners under the same mechanisms.

Some pools pay miners for their work regardless of if the pool finds a block or not, but when they do, the pool operator keeps the block rewards. Others only pay them after finding a block, distributing the block rewards among all miners. In this case, the pool operators charge a fee to the miners.

Closing thoughts

In conclusion, many factors affect Bitcoin mining revenue. If you want to start mining, you must know how hashrate, difficulty, fees, and mining pools determine how much you will earn.

Understanding how mining revenue works will enable you to better calculate your profitability. As a result, you’ll be able to adapt to any unexpected situations that could affect your mining operation.
