The Bitcoin halving event is a cornerstone of cryptocurrency economics, occurring approximately every four years. It reduces the block reward miners receive by 50%, directly impacting Bitcoin's supply-demand dynamics and price. Three halvings have occurred since Bitcoin's inception, with the fourth anticipated in April 2024.

What Is Bitcoin Halving?
Bitcoin halving is a preprogrammed event in Bitcoin's protocol that slashes mining rewards by half every 210,000 blocks (roughly four years). Key aspects:
- Deflationary Design: Bitcoin’s fixed supply cap of 21 million coins ensures scarcity.
- Mining Rewards: Initial block reward was 50 BTC (2009), reduced to 25 BTC (2012), 12.5 BTC (2016), and 6.25 BTC (2020).
- Final Halving: Expected in 2140, after which miners will earn only transaction fees.
