Bitcoin's protocol halves the subsidy in the coinbase transaction every 210,000 blocks. The reward went from 50 BTC (2009) to 25 (2012), 12.5 (2016), 6.25 (2020), and 3.125 BTC (2024). Because new supply decreases while demand may hold or g

1. What Is the Bitcoin Halving
The Bitcoin halving is a scheduled event, roughly every four years, that cuts the block reward miners receive in half. It is the mechanism that enforces Bitcoin's fixed 21 million supply cap and its disinflationary monetary policy.
2. How It Works
Bitcoin's protocol halves the subsidy in the coinbase transaction every 210,000 blocks. The reward went from 50 BTC (2009) to 25 (2012), 12.5 (2016), 6.25 (2020), and 3.125 BTC (2024). Because new supply decreases while demand may hold or grow, halvings have historically coincided with bull markets, though the mechanism itself only affects issuance, not price directly.
3. Why It Matters
The halving is central to Bitcoin's value proposition of scarcity and predictability. It also stresses miner economics — those with higher costs may be forced out, affecting network hashrate and security. Halving cycles drive much of the narrative, trading, and market structure around Bitcoin.
4. Key Facts
- Next halving expected in early 2028 (block 1,050,000)
- Total supply is capped at 21,000,000 BTC
- After ~2140 the subsidy rounds to zero; miners earn only fees
- Historical halvings: Nov 2012, Jul 2016, May 2020, Apr 2024
