Since its inception, Bitcoin (BTC) has experienced a halving event approximately every four years, which reduces miner rewards by half. This mechanism decreases the supply of Bitcoin and typically triggers changes in market supply and demand after a halving, driving up prices and forming a bull market cycle. Historical data shows that price peaks often occur in the second year after a halving. However, as the market matures and external factors come into play, the regularity of this four-year cycle may gradually weaken.
