$BTC Bitcoin’s Fourth Halving – April 2024
Bitcoin’s fourth block reward halving occurred on April 20, 2024, at block height 840,000, reducing the block reward from 6.25 BTC to 3.125 BTC in line with Bitcoin’s fixed issuance schedule.
As a result, daily issuance dropped from ~900 BTC to 450 BTC, and annual issuance from ~328,500 BTC to 164,250 BTC, lowering Bitcoin’s annual supply inflation to approximately 0.83%—below that of gold and independent of monetary policy decisions.
By the end of 2024, Bitcoin’s circulating supply is estimated at around 19.7 million BTC, with over 93.8% of the total 21 million BTC already mined. The halving also shifts miner revenue toward transaction fees, reinforcing Bitcoin’s long-term transition to a fee-based security model.
This halving is irreversible, transparent, and enforced by network consensus, further cementing Bitcoin’s predictable and mathematically defined monetary policy ahead of the next halving expected around 2028.
