As a consultant who advises entrepreneurs on evaluating new business opportunities, I often get asked about Bitcoin mining. With the immense interest and volatility around cryptocurrencies, many see mining as a potential revenue stream. But how lucrative is Bitcoin mining today?
In 2023, approximately 900 bitcoins are mined per day. However, this number fluctuates based on Bitcoin‘s built-in mining protocols and the total computing power dedicated to mining. By understanding how Bitcoin mining works, small businesses can make informed decisions on opportunities in this space.
A Brief Introduction to Bitcoin Mining
Bitcoin mining involves using specialized computers to solve complex math problems that validate transactions on the Bitcoin network. These math problems are part of Bitcoin‘s proof-of-work consensus mechanism that secures the blockchain.
When miners successfully solve a problem, they receive a fixed Bitcoin block reward (currently 6.25 BTC) plus any transaction fees from that block. This provides the economic incentive to dedicate computing power to the network.
The difficulty of the math problems automatically adjusts every 2 weeks to maintain an average block time of 10 minutes. If more computing power joins the network, problems become harder to solve.
How Many New Bitcoins? Daily Mining Issuance Rates
On average, 144 blocks are mined each day on the Bitcoin network. At the current block reward rate of 6.25 BTC per block, approximately 900 new bitcoins are issued each day through mining.
However, the exact amount can vary daily due to several factors:
- Block time variance: Block times are not perfectly consistent, which affects the number of blocks mined.
- Transaction fees: Miners also earn fees attached to each transaction, which vary day to day.
- Network hash rate: If network computing power changes, so does the difficulty to maintain 10 minute block times. This impacts block issuance.
Here is a table showing estimated Bitcoin mining issuance over time:

As shown, the Bitcoin protocol reduces block rewards by 50% every 4 years. This will gradually trend issuance lower over time until all 21 million bitcoins are mined by the year 2140.
Is Bitcoin Mining Profitable for Small Businesses?
When Bitcoin‘s price is high, mining can be very profitable, attracting more miners to the network. But when the price drops, profitability declines, forcing out the least efficient miners.
Home Bitcoin mining is generally not profitable for small businesses today due to rising network difficulty and electricity costs. Dedicated mining operations with access to low-cost power tend to dominate the market.
However, mining profitability ultimately depends on:
- Bitcoin price – The higher the price, the more revenue miners receive.
- Network difficulty – Rising difficulty decreases profit margins.
- Hash rate – More mining power means dividing rewards among more miners.
- Power costs – The main operational expense for miners is electricity.
- Mining equipment – Specialized ASIC hardware is expensive but efficient.
- Mining pool fees – Pools charge fees for coordinating group mining efforts.
With constantly changing conditions, small businesses should thoroughly research costs, risks, and likely returns before investing in Bitcoin mining equipment. Profitability calculators can model potential revenue based on assumptions.
In summary, approximately 900 new bitcoins are mined per day in 2023, worth over $20 million. However, mining revenues fluctuate daily based on Bitcoin‘s protocol rules, market economics, and hash rate growth. While Bitcoin mining can be lucrative, small businesses should carefully assess profitability before jumping in. As a consultant, I help entrepreneurs model the risks and rewards of new opportunities like Bitcoin mining.
