In the next decade, Bitcoin block rewards will decrease significantly. This has implications for miners and the overall blockchain ecosystem. Bitcoin halvings occur every four years, offering some predictability in terms of when new coins will be introduced to the market.
Currently, 93% of Bitcoin’s total supply is already in circulation, making it increasingly challenging to mine new coins. The latest halving in 2020 reduced block rewards to just 6.25 BTC every 10 minutes, further decreasing to 3.125 BTC per block.
While the number of Bitcoin available for mining has decreased, the value of each coin has surged. In 2012, 50 BTC were worth $600, whereas now 3.125 BTC can be valued at hundreds of thousands of dollars.
Future Bitcoin halvings will continue to reduce block rewards, with the next one expected in 2028, resulting in 1.5625 BTC per block. The diminishing rewards will push miners to rely more on transaction fees for income.
As the mining landscape evolves, mergers and acquisitions are likely to increase to reduce costs and drive efficiency. While this may lead to some centralization, it is essential for miners to remain economically viable.
The 2024 halving presents unique challenges and opportunities, especially with the recent surge in Bitcoin’s price and the launch of Bitcoin ETFs in the U.S. Miners will need to adapt to these changing market conditions to ensure their sustainability.
