Bitcoin Halving Atlas
Roughly every four years (210,000 blocks) the Bitcoin block reward halves, cutting new supply in half. Below is a live countdown to the fifth halving at block 1,050,000 — plus a systematic look at what each prior supply shock did to price. For educational purposes only.
The halving era atlas
Each prior era ran up to a cycle peak roughly 12–18 months after the halving, then gave back the majority of the move. The magnitude of every advance has shrunk cycle-over-cycle — and so has the depth of the drawdown.
