Bitcoin Halving Countdown
Track the countdown to the next Bitcoin halving, including estimated timing, remaining blocks, and the scheduled reduction in block rewards.
COUNTDOWN TO THE
NEXT BITCOIN HALVING
Blocks remaining, reward schedule, and context for Bitcoin’s next supply milestone.
Estimated date & time: 19 April 2028, 03:38 UTC.
The Bitcoin block subsidy will decrease from 3.125 BTC to 1.5625 BTC.
Next halving will be at block 1,050,000
What Is the Bitcoin Halving?
The next Bitcoin halving will take place at block 1,050,000. At that point, the Bitcoin block subsidy will fall from 3.125 BTC to 1.5625 BTC per block.
The countdown above provides an estimated date and time based on the current Bitcoin block height and recent block production. However, the exact date may move forward or backward because the halving is activated by a specific block height—not by a fixed calendar date.
Bitcoin blocks are produced roughly every 10 minutes on average, but individual blocks may arrive faster or slower. For this reason, the estimated Bitcoin halving date becomes more accurate as block 1,050,000 approaches.How Does the Bitcoin Halving Work?
Bitcoin miners use computing power to process transactions, produce new blocks and help secure the network. When a miner successfully produces a valid block, the miner can receive newly issued bitcoin through the block subsidy, together with the transaction fees included in that block.
Bitcoin’s subsidy began at 50 BTC per block in 2009. The protocol reduces this subsidy by half after every 210,000 blocks, which usually takes approximately four years.
I remember when one block produced 50 BTC and I was trying to mine Bitcoin using my laptop’s graphics card. At the time, Bitcoin mining was still accessible to ordinary computer users. Today, mining is a highly competitive global industry that relies mainly on specialised ASIC hardware and access to efficient energy. Check here to know the bitcoin mining difficulty.
Bitcoin Halving History
Bitcoin has completed four halvings since the network launched. Each event has reduced the block subsidy according to the schedule encoded in the Bitcoin protocol. The historical halving blocks and rewards can be independently verified through the Bitcoin blockchain.
| Event | Block | Date | New Block Subsidy |
|---|---|---|---|
| Bitcoin launch | 0 | 3 January 2009 | 50 BTC |
| First halving | 210,000 | 28 November 2012 | 25 BTC |
| Second halving | 420,000 | 9 July 2016 | 12.5 BTC |
| Third halving | 630,000 | 11 May 2020 | 6.25 BTC |
| Fourth halving | 840,000 | 20 April 2024 UTC | 3.125 BTC |
| Fifth halving | 1,050,000 | Estimated in 2028 | 1.5625 BTC |
Future halving dates cannot be known with complete precision. The block heights and subsidy reductions are fixed, but the calendar dates depend on how quickly miners produce the remaining blocks.
What Happens When All Bitcoin Has Been Mined?
Bitcoin’s block subsidy will continue to become smaller through future halvings. Eventually, the issuance of new BTC will stop and miners will no longer receive newly created bitcoin as part of their reward.
At that stage, miners are expected to depend primarily on transaction fees paid by Bitcoin users. The transition will happen gradually over many decades rather than immediately after a single halving.
