What is Bitcoin halving

Bitcoin halving is a built-in event that cuts the reward miners earn for confirming transactions by 50%, happening roughly every four years until the total supply of 21 million coins is mined. It matters because it slows the rate of new bitcoin entering circulation, which has historically preceded major price cycles as supply growth shrinks while demand stays the same or grows. The next question most people ask: when's the next one? The last halving hit in April 2024, dropping the reward from 6.25 BTC to 3.125 BTC per block. The next is expected around 2028, when it will fall again to 1.5625 BTC. Halvings continue until around the year 2140, when the last fraction of bitcoin gets mined and rewards stop entirely, leaving miners to rely on transaction fees alone.
