What is a Bitcoin Halving?
Bitcoin halving is a pre-programmed event in Bitcoin's protocol that reduces the block reward miners receive by 50%. Occurring approximately every four years (after 210,000 blocks), this mechanism controls Bitcoin's inflation rate by slowing new supply issuance. With only 21 million BTC ever to exist, halvings ensure Bitcoin remains a deflationary asset.
Why it matters:
- Scarcity increases as new supply slows
- Historically triggers bull markets due to supply-demand dynamics
- Reinforces Bitcoin's "digital gold" narrative

The Stock-to-Flow Model
This economic model measures scarcity by comparing existing supply (stock) to new issuance (flow). Key predictions:
- Bitcoin will surpass gold's scarcity by 2025
- Post-2024 halving could trigger unprecedented S2F ratios
- Long-term price targets align with historical bull cycles
FAQs About Bitcoin Halving
