The halving is one of the most important events in Bitcoin's calendar.
What is the Halving?
Every 210,000 blocks (approximately every 4 years), the block reward given to miners is cut in half.
Halving History
2009: 50 BTC reward → 2012: 25 BTC → 2016: 12.5 BTC → 2020: 6.25 BTC → 2024: 3.125 BTC → ~2028: 1.5625 BTC
Why it Matters
- Supply shock: Fewer new Bitcoin entering circulation
- Historically: Each halving has preceded a significant price increase (12–18 months later)
- Inflation rate: Bitcoin's inflation rate drops to near zero over time
- Fixed supply: The last Bitcoin will be mined around 2140
⚠️ The halving does NOT guarantee price increases. Past cycles are not a guarantee of future performance.
