What Is Bitcoin Halving?
Bitcoin halving is a pre-programmed event in Bitcoin's blockchain protocol that cuts the mining reward in half approximately every four years. This built-in mechanism controls Bitcoin's inflation rate and enforces its 21 million supply cap.
Key features of Bitcoin halving:
- Triggers every 210,000 blocks (~4 years)
- Reduces new BTC issuance by 50%
- Guarantees fixed maximum supply
- Maintains Bitcoin's deflationary design

Why Bitcoin Halving Matters
The halving cycle is central to Bitcoin's value as digital scarcity. Unlike central banks that print money indefinitely, Bitcoin follows a transparent, algorithmic monetary policy:
- Predictable supply schedule
- Decreasing inflation rate
- Increasing stock-to-flow ratio
- Hedge against currency devaluation
This programmed scarcity mirrors precious metals' economics while offering digital advantages - creating what many call "sound money for the internet age."
