Bitcoin Halvings

Bitcoin AI

Halvings, bull and bear markets — Bitcoin AI can put the history in context.

Current era

Fourth halving

19 April 2024

Supply cut

Every 210,000 blocks (~4 years) the block reward halves, permanently slowing new Bitcoin supply.

Reward history

Started at 50 BTC per block in 2009. Now 3.125 BTC after four halvings.

Historical pattern

Each of the first three halvings preceded a major bull run within 12–18 months.

Inflation rate

Post-fourth halving, Bitcoin's annual issuance rate fell below 1% — lower than gold.

Final issuance

The last BTC won't be mined until ~2140, when the block reward approaches zero.

Bitcoin Halvings

Bitcoin halvings reduce the block reward miners receive, cutting the rate at which new bitcoin enters circulation. Historically, halvings have coincided with major bull runs as supply growth slows.

The all-time daily chart marks each halving with a white vertical line so you can see full-history context before drilling into per-halving views.
