What Is Bitcoin Halving?
Bitcoin halving is a built-in event, written into Bitcoin’s code from the start, that cuts the reward miners receive for adding a new block to the blockchain in half. It happens automatically every 210,000 blocks — roughly every four years, since Bitcoin averages one new block every 10 minutes.
Why Halving Matters
Halving is the mechanism that enforces Bitcoin’s fixed supply of 21 million coins. Every time it happens, new bitcoin enters circulation at half the previous rate, making Bitcoin more scarce over time in a way that is predictable and cannot be changed by any single person, company, or government. Past halvings have historically been followed by significant shifts in market activity, though past patterns are not a guarantee of future price behavior.
How the Countdown Works
The estimate above is based on Bitcoin’s current block height and its long-run average block time of about 10 minutes. Because actual block times vary with network hash rate and difficulty adjustments, the exact date can shift slightly as the halving approaches — this page recalculates it from live block height data rather than showing a single fixed date.
