The 100-Day Window

Bitcoin cycle countdown, explained plainly

After each major bull-market top, Bitcoin has historically spent roughly a year in drawdown before the next cycle low. Cryptological tracks days remaining against that average, measured from the October 2025 peak.

This is a historical compass, not a price prediction. Past cycles varied in length; the counter helps patient holders prepare during the quietest phases.

How the countdown is calculated

Three methods cluster around late October 2026: all three top→bottom phases average 382 days (~23 Oct), bottom-to-bottom spacing averages 1435 days (~26 Oct), and the last two bears average 370 days (~11 Oct). Cryptological uses the 370-day line deliberately, to bias preparation ahead of the window. Days left equals 370 minus days elapsed since the 6 October 2025 peak.

Newsletter #1 and the October 2025 moment

Cryptological Newsletter #1 (29 August 2025) included a Market Overview screenshot where cycle-length indicators, based on historical averages, were already clustering around October 2025. A short YouTube walkthrough from 9 October 2025 explains when an indicator briefly read 0 days left til cycle bottom, days after the 6 October top. Educational context only, not financial advice.

A free weekend with full chart access is planned so visitors can explore the same cycle tools during the current post-peak window. Past cycles varied; historical patterns do not predict future prices.
