Bitcoin Price Cycles: A Four-Year Pattern Explained
Bitcoin's price history has followed a roughly four-year rhythm since its earliest years โ a pattern closely tied to, though not perfectly explained by, its halving schedule. Understanding this cycle is one of the most common entry points into deeper Bitcoin market analysis.
The cycle pattern historically observed
| Cycle | Approx. Bottom | Approx. Peak | Peak-to-Trough Decline |
|---|---|---|---|
| 1 | 2011 (~$2) | Nov 2013 (~$1,100) | ~85% |
| 2 | Jan 2015 (~$150) | Dec 2017 (~$19,700) | ~84% |
| 3 | Dec 2018 (~$3,200) | Nov 2021 (~$69,000) | ~77% |
| 4 | Nov 2022 (~$15,500) | Oct 2025 (~$126,198) | ~52%+ (ongoing as of 2026) |
What's believed to drive the pattern
The dominant explanation ties the cycle to Bitcoin's halving schedule: reduced new supply following each halving, combined with periods of growing demand, has historically preceded major bull runs, followed eventually by profit-taking and a multi-year correction once the market becomes overextended relative to near-term demand.
Why some analysts now question whether the pattern holds
Several structural changes distinguish the current era from Bitcoin's first three cycles: spot ETFs didn't exist before 2024; corporate treasury holdings were negligible before 2020; and the overall market capitalization has grown so large that historical percentage moves may simply be less repeatable at the current scale. Some analysts argue the four-year cycle is becoming less pronounced as Bitcoin matures into a more broadly-held, institutionally-integrated asset; others maintain the underlying halving-driven supply mechanics will continue to matter regardless of who's holding the coins.
Past cycle patterns, however consistent historically, are not a guarantee of future price behavior. This article is educational and not a price prediction.
