Bitcoin Halving Countdown
Live timer to block 1,050,000 — when the block reward drops from 3.125 to 1.5625 BTC.

What is the Bitcoin halving?
Every 210,000 blocks — roughly every four years — the reward miners earn for adding a block is cut in half. It's the mechanism that enforces Bitcoin's fixed 21-million supply: new coins enter circulation on a schedule that slows relentlessly until the last fraction is mined around 2140. The 2028 halving at block 1,050,000 will cut daily new supply from roughly 450 BTC to 225 BTC — overnight. Read our full explainer on how the halving works and its historical impact for the deeper mechanics.
Past halvings and what followed
| Halving | Block | Reward | Price then | Cycle peak after |
|---|---|---|---|---|
| November 28, 2012 | 210,000 | 50 → 25 BTC | ~$12 | ~$1,100 within a year |
| July 9, 2016 | 420,000 | 25 → 12.5 BTC | ~$650 | ~$20,000 by Dec 2017 |
| May 11, 2020 | 630,000 | 12.5 → 6.25 BTC | ~$8,700 | ~$69,000 by Nov 2021 |
| April 20, 2024 | 840,000 | 6.25 → 3.125 BTC | ~$64,000 | ~$126,000 by Oct 2025 |
Four data points do not make a law — past cycles are history, not a forecast.
Why the halving matters
This countdown tracks the real Bitcoin blockchain, not a calendar. The timer reads the current block height live from mempool.space and estimates the moment block 1,050,000 will be mined, assuming the network's ten-minute average block time. Because actual block times wobble with mining power, the date shifts slightly from day to day — that's not a bug, it's how Bitcoin actually works. Difficulty adjustments keep the long-run schedule remarkably tight: four halvings have arrived within weeks of their four-year marks.
Why do people care so much? Supply and demand. Each halving cuts the flow of new Bitcoin hitting the market in half while demand stays whatever it is — and the three completed cycles before 2024 each saw dramatic bull markets in the twelve to eighteen months that followed. Whether that pattern holds is the trillion-dollar question, and this is exactly where discipline beats prediction. See what past cycles actually paid with our If You Had Invested calculator, or test the strategy most long-term holders use through halving cycles — steady monthly buying — with the Bitcoin DCA calculator.
One more thing the halving guarantees: mining economics change overnight, miner revenue halves, and the asset becomes scarcer to produce than gold by any flow measure. The full story — mechanics, history, and what it means for fees and security — is in our halving deep-dive.
Stacking before the halving?
Set up recurring buys on Binance and move your stack to a Ledger hardware wallet — the strategy that survived every cycle so far is boring: accumulate, self-custody, wait.
Disclaimer: The halving date is an estimate based on the current block height and a ten-minute average block time — the actual date shifts with real block production and cannot be known precisely in advance. Past price behavior around halvings does not guarantee future results. Nothing on this page is financial advice — always do your own research.
