When is the next Bitcoin halving?

The next Bitcoin halving is expected around April 2028, at block 1,050,000. The exact date depends on the average block time between now and then. Bitcoin halvings occur every 210,000 blocks, approximately every 4 years.

What happens to Bitcoin mining after the 2028 halving?

The 2028 halving will reduce the block reward from 3.125 BTC to 1.5625 BTC per block. This cuts mining revenue in half overnight unless the BTC price compensates. Historically, halvings have been followed by significant BTC price appreciation, which has more than offset the revenue reduction for efficient miners.

Bitcoin Halving — Frequently Asked Questions

When exactly is the 2028 Bitcoin halving? +

The 5th Bitcoin halving occurs at block 1,050,000. Based on current block production pace (~10 minutes per block), the estimated date is around April 2028 — but this shifts as actual block times vary. Use the live countdown above for the most accurate estimate based on real-time block height data from mempool.space.

How does the halving affect Bitcoin mining profitability? +

The halving cuts the block subsidy in half, directly reducing miner revenue by 50% overnight (assuming BTC price stays constant). Historically, BTC price has risen substantially in the months following each halving, which has more than compensated miners. Use our Difficulty Forecast and ROI Calculator to model specific scenarios for your hardware.

What is the current Bitcoin block reward? +

The current Bitcoin block reward is 3.125 BTC per block, following the April 2024 halving (the fourth halving overall). Miners also earn transaction fees in addition to the block subsidy. Total mining rewards (subsidy + fees) are visible on mempool.space block explorer.

How many Bitcoins are left to mine? +

Bitcoin has a fixed supply cap of 21 million coins. As of 2026, approximately 19.8 million BTC have been mined, leaving around 1.2 million BTC still to be issued. The last Bitcoin is projected to be mined around 2140, as block rewards halve every four years and approach zero asymptotically.

Should I buy an ASIC miner before or after the halving? +

Buying before the halving means you earn more BTC per day now but face a revenue cut at the halving. Buying after the halving means lower immediate revenue but potentially higher BTC prices. The key variable is your expected electricity cost — at sub-$0.05/kWh with efficient hardware, mining can remain profitable through a halving cycle even without a BTC price increase. Use our ROI Calculator to model both scenarios for your specific miner.
