Bitcoin Halving Countdown
Live countdown to the 5th Bitcoin halving at block 1,050,000, when the block reward drops from 3.125 BTC to 1.5625 BTC. Estimate is based on the current block height assuming a 10-minute average block time.
What is the Bitcoin halving?
Every 210,000 blocks — roughly every four years — Bitcoin's block reward is cut in half. This hard-coded supply schedule is built directly into the protocol. It steadily reduces the rate of new BTC entering circulation until the maximum supply of 21,000,000 BTC is reached around the year 2140.
Each halving has historically preceded a major bull cycle, though the sample size is tiny (4 events) and past performance is no guarantee. What's certain is that halvings cut miner revenue overnight — pushing inefficient miners offline and tightening the structural sell pressure from newly minted coins.
