Bitcoin’s next halving event is now just one week or approximately 1,000 blocks away, according to The Block’s Bitcoin Halving Countdown page.
The estimated countdown is based on Bitcoin’s average block generation time of 10 minutes, setting a potential date of April 20 at around 9 a.m. UTC (5 a.m. ET), to reach the next halving block height of 840,000, as things stand. Bitcoin’s next halving event will see the subsidy reward for miners on the network drop from 6.25 BTC to 3.125 BTC per block.
Bitcoin halvings are programmed to occur automatically every 210,000 blocks — roughly every four years. Once a halving event occurs, miners receive 50% fewer bitcoins as a subsidy reward for every block of transactions they mine and add to the blockchain. However, they continue to earn additional transaction fee rewards for each block mined as normal.
There have been three halving events in Bitcoin’s history, reducing its block subsidy inflation from 50 BTC to 25 BTC in 2012, then to 12.5 BTC in 2016 and 6.25 BTC at the last halving on May 11, 2020. In the long term, there will only ever be 21 million bitcoins in existence.
The halving events will continue until the last bitcoin is expected to be mined around the year 2140. After this, miners will only earn from transaction fees.
