Bitcoin's entire history runs on a four-year clock. Here it is on one chart — every halving, every bottom, every top — and what that rhythm suggests (and can't promise) about what comes next.
Bitcoin's price (log scale) since 2010. Orange dashes = the four halvings. Green zones = the ~18 months after each halving, where every major bull run so far ignited. Markers show each cycle's bottom and top. Hover or tap to explore.
Miners earn brand-new Bitcoin with every block they add to the chain. Every four years that paycheck is cut in half — it's written into Bitcoin's code and cannot be changed.

Miners sell coins to pay their bills. After a halving, half of that daily selling pressure disappears. Same buyers, fewer new coins — that squeeze has historically pushed prices up over the following months.
The same shape has played out after all four halvings: a quiet wait, then momentum roughly 6–12 months later, a peak about a year to 18 months after, then the long cool-down into the next cycle's bottom.
| # | Halving date | Block reward | Price that day | Cycle peak (within ~18 mo) | Gain to peak |
|---|---|---|---|---|---|
| 1 | Nov 28, 2012 | 50 → 25 BTC | ~$12 | ~$1,130 · Nov 2013 | ≈ 94x |
| 2 | Jul 9, 2016 | 25 → 12.5 BTC | ~$650 | ~$19,700 · Dec 2017 | ≈ 30x |
| 3 | May 11, 2020 | 12.5 → 6.25 BTC | ~$8,600 | ~$69,000 · Nov 2021 | ≈ 8x |
| 4 | Apr 20, 2024 | 6.25 → 3.125 BTC | ~$63,800 | ~$124,800 · Oct 2025 | ≈ 2x |
Bitcoin's four cycle bottoms so far are Nov 2011, Jan 2015, Dec 2018 and Nov 2022. Feed those dates into a handful of simple statistical rules and each one spits out a guess for the next bottom. None of them know the future — but it's honest to show what the clock alone would say:
| Model (plain English) | How it thinks | Its guess |
|---|
Community analyses of the ~700 biggest coins in each cycle (including the dead ones — the part most people never see) tell a story most influencers skip. The numbers below are approximate and illustrative, but the direction is unmistakable:
Understanding where you are in the cycle is step one. Knowing what to do about it — sizing, exits, security — is what the free course teaches.
