Bitcoin Halving Countdown

The Bitcoin halving is a pre-programmed event built into Bitcoin's protocol that cuts the block reward — the amount of new BTC created with each block — in half. It occurs every 210,000 blocks, approximately every four years. The halving ensures Bitcoin's supply follows a disinflationary schedule, gradually reducing the issuance rate until the maximum supply of 21 million BTC is reached around the year 2140.

The next Bitcoin halving will occur at block 1,050,000. The exact date cannot be predicted precisely because block times vary, but it is estimated to happen in early 2028 based on the average 10-minute block interval. This countdown page shows the real-time estimate based on current block height.

The halving matters because it directly impacts Bitcoin's supply economics. When the block reward is cut in half, miners produce 50% less new BTC per day. If demand remains constant or grows while new supply decreases, basic economics suggests upward price pressure. Historically, each halving has preceded significant bull runs — though correlation does not imply causation, and past performance doesn't guarantee future results.

Four halvings have occurred so far: November 2012 (50→25 BTC), July 2016 (25→12.5 BTC), May 2020 (12.5→6.25 BTC), and April 2024 (6.25→3.125 BTC). The current block reward is 3.125 BTC per block, and the next halving will reduce it to 1.5625 BTC.

Historically, Bitcoin's price has increased significantly in the 12-18 months following each halving. After the 2012 halving, BTC rose from ~$12 to over $1,000. After 2016, it went from ~$650 to ~$2,500 within a year (and eventually $20,000). After 2020, it rose from ~$8,800 to ~$56,000 within a year. However, many other factors influence price, and past patterns may not repeat.

The halving immediately cuts miners' BTC revenue in half. Miners with high electricity costs or inefficient hardware may become unprofitable and shut down. This can temporarily reduce the network hash rate until difficulty adjusts. Over time, miners adapt through more efficient hardware, cheaper energy, and the expectation that BTC price appreciation will compensate for the reduced reward.

The last Bitcoin is expected to be mined around the year 2140. At that point, miners will earn revenue solely from transaction fees rather than block rewards. However, over 99% of all Bitcoin will be mined well before then — by approximately 2032, over 99% of the 21 million supply will have been issued.
