Bitcoin’s astir 50% diminution from the October 2025 highest is inactive successful enactment with anterior rhythm behaviour by depth, slope, and timing. Prior rhythm lows followed astir 12 months aft the peak, and the existent setup points to a Q4 2026 debased window.

The Four-Year Cycle Framework
Bitcoin has moved successful a four-year signifier since its archetypal traded cycle. Peaks person arrived successful precocious 2013, precocious 2017, precocious 2021, and precocious 2025. Troughs person followed astir 12 months later: January 2015, December 2018, November 2022. The signifier has held crossed 3 implicit cycles careless of the prevailing narrative, retail-driven successful 2017, institutional-curious successful 2021, ETF-enabled & Bitcoin treasury companies successful 2025.
Each rhythm is anchored by the halving, which compresses caller proviso connected a fixed schedule, and amplified by reflexive demand: rising terms draws marginal capital, marginal superior lifts terms further, leverage builds, and the operation yet breaks.

| 4 (current) | October 2025 | TBD (Q4 2026 basal case) | - | 50% (current) |
The Decline Sits Mid-Pattern by Magnitude
The 50% selloff is shallow comparative to the 77–85% organisation of anterior rhythm declines. Measured against clip elapsed astatine the 7-month people from peak, the existent diminution tracks anterior periods closely:
| Cycle | Drawdown 7 Months After Peak | Final Drawdown |
| 2017–2018 | Around −65% | −84% |
| 2021–2022 | Around −65% | −77% |
