Every 210,000 blocks mined roughly once every four years - the reward that Bitcoin miners receive for validating transactions gets cut in half. This event is called the halving. In the early days miners earned 50 BTC per block; today the reward sits at 3.125 BTC after the April 2024 halving. The reason the community treats halving as a significant date on the calendar is simple: if demand stays flat or grows while the daily supply of new coins drops, basic economics suggests price should respond positively. History has backed this theory so far each of the previous four halvings was eventually followed by a major bull market. The next halving is projected around early 2028, and many analysts are already incorporating it into their long-term price models.
