What Is the Bitcoin Halving and How Does It Affect Miners?
Every four years, mining rewards get cut in half. Here's what that means for your operation.
The halving explained
Every 210,000 blocks (~4 years), the Bitcoin block reward is cut in half. The most recent halving in April 2024 reduced the reward from 6.25 to 3.125 BTC. The next halving (~2028) will reduce it to 1.5625 BTC.
Impact on miners
In the short term, miners earn fewer BTC per block. Less efficient miners may become unprofitable and shut down. This reduces competition, which partially offsets the revenue hit for remaining miners.
The price factor
Historically, halvings have preceded significant BTC price increases. If price doubles while rewards halve, miners maintain similar USD revenue. Past performance doesn't guarantee future results, but the supply-reduction thesis is simple economics.
Strategy
The best defense against halvings is efficiency. Miners running the most efficient hardware at the lowest electricity costs survive and thrive through halvings. This is why upgrading hardware and hosting at low-cost facilities matters.
