Bitcoin Halving
Every ~4 years, Bitcoin's block reward is cut in half. Here's everything you need to know.
What is the halving?
The Bitcoin halving is a programmatic event built into Bitcoin's code that reduces the reward paid to miners for validating blocks by 50%. It occurs every 210,000 blocks (~4 years) and continues until all 21 million BTC are mined (estimated ~2140).
Halving history
• Block 0 (2009) — Reward: 50 BTC
• Block 210,000 (Nov 2012) — Reward: 25 BTC
• Block 420,000 (Jul 2016) — Reward: 12.5 BTC
• Block 630,000 (May 2020) — Reward: 6.25 BTC
• Block 840,000 (Apr 2024) — Reward: 3.125 BTC
• Block 1,050,000 (~2028) — Reward: 1.5625 BTC
Why it matters for price
The halving reduces the rate of new Bitcoin supply. Basic economics: if demand stays constant or grows while supply growth slows, upward price pressure increases.
Historically, Bitcoin has entered bull markets 12–18 months after each halving. Past halvings are not a guarantee of future performance — but they are structurally significant.
