Halving
A built-in Bitcoin event that cuts the mining reward in half roughly every four years, slowing the rate of new Bitcoin creation—and historically, it's been followed by price increases.
Every four years or so (every 210,000 blocks), Bitcoin's code automatically cuts the reward miners get in half. It started at 50 BTC per block back in 2009, dropped to 25 in 2012, then 12.5 in 2016, 6.25 in 2020, and 3.125 in 2024.
Why does this matter? It directly reduces how fast new Bitcoin enters the market. If demand stays the same (or grows) while supply creation drops, basic economics says prices should feel upward pressure. And historically, that's exactly what's happened—Bitcoin's price has risen significantly in the 12-18 months after each halving.
The halving schedule is completely predictable and will keep going until all 21 million Bitcoin are mined—estimated around the year 2140. After that, miners will only earn transaction fees, and no new Bitcoin will ever be created.
For miners, halvings are a big deal—their revenue gets cut in half overnight (assuming prices stay flat). Less efficient miners get pushed off the network, temporarily reducing the total computing power (hash rate). Over time, the survivors benefit from less competition and, historically, rising prices.
Now, a word of caution: while all four halvings have preceded bull markets, that's a sample size of just four. Each cycle had different conditions—different levels of institutional involvement, different regulations, different macroeconomic backdrops. Halvings reduce new supply, but price ultimately depends on demand, which is shaped by adoption, regulation, and the broader economy.
Frequently Asked Questions
▸When is the next Bitcoin halving?
The most recent halving was in April 2024, bringing the block reward down to 3.125 BTC. The next one is expected around 2028, when the reward will drop to 1.5625 BTC per block.
▸Does halving guarantee a price increase?
No guarantees. All four historical halvings were followed by significant price increases (usually months later), but past performance doesn't promise future results. Markets may also start pricing halvings in ahead of time as they become more widely understood.
