Crypto analyst Cryptobirb argues that Bitcoin may be approaching the final stretch of its current market cycle, with a probable peak forming between late October and late November 2025. The projection is based on a historical framework that combines Bitcoin halving dates, prior bull-market durations, and the timing of past cycle tops.
Halving Data Remains Central to the Thesis
In an Aug. 14 post on X, Cryptobirb said Bitcoin’s historical behavior after halving events continues to offer useful clues about when the asset is most likely to top. According to the analyst, Bitcoin reached its peak roughly 366 days after the first halving, while later cycles showed tops occurring more than 500 days after the event. With the latest halving having taken place on April 19, 2024, the analyst said the market has already advanced far enough in the post-halving timeline to suggest that the final phase of the bull cycle may now be underway.
Using the Bitcoin Cycle Peak Countdown model, Cryptobirb estimates that the current bull market is tracking toward a total duration of about 1,060 to 1,100 days. The model uses Nov. 21, 2022 as the cycle low, and the analyst said the market is now at approximately day 997 from that bottom. From that perspective, Bitcoin appears to be closing in on the range where prior cycle tops have tended to form.
A Narrower Window for the Cycle Top
Based on this historical setup, Cryptobirb believes the highest odds for a cycle peak fall within a relatively tight period in the fourth quarter of 2025. The broader forecast places the likely top between Oct. 19 and Nov. 20, 2025. The analyst also described a more concentrated “sweet spot” between Oct. 15 and Nov. 15, 2025, suggesting that the next three months are especially important for traders monitoring late-cycle signals.
The thesis is not based on halving analysis alone. Cryptobirb also examined the duration of Bitcoin’s previous four bull markets. The 2010–2011 rally lasted less than a full calendar year, while the 2011–2013 cycle extended to 746 days. Since then, each bull market has lasted more than 1,000 days. In that context, the current cycle appears consistent with a mature but not yet fully exhausted bull trend, one that could culminate within the projected 1,060–1,100 day range.
Seasonality and Market Behavior
Another element supporting the forecast is seasonality. Although Bitcoin has already logged multiple milestones this year, Cryptobirb said October and November have historically been the asset’s strongest months. In the analyst’s view, these months have delivered the best average gains and the highest concentration of all-time highs, making them especially relevant in the search for a possible market top.
This historical tendency does not guarantee a repeat, but it helps explain why the analyst sees the fourth quarter as the most probable window for a climax in the current cycle. The argument is essentially that the market’s timing, duration, and seasonal performance are now aligning in a way that resembles previous late-stage bull markets.
What Could Follow in 2026
Cryptobirb also warned that bear markets have shown patterns of their own. According to the analyst’s historical review, Bitcoin bear markets typically last between 370 and 410 days, with an average drawdown of around -66%. If the current cycle does peak in late 2025, that framework would imply a more difficult market environment in 2026.
That does not mean a downturn would begin immediately or unfold identically to previous cycles. Still, the analyst’s message is clear: participants should be thinking not only about upside targets, but also about capital preservation once the market enters a late-cycle phase. In practical terms, the post-peak period has historically rewarded discipline more than aggression.
Positioning for a Late-Cycle Market
For traders and investors, Cryptobirb’s recommendation is to prepare rather than react. The analyst urged followers to plan exits, reduce leverage, and take profits while the market remains constructive. The goal, according to the post, is not to call the exact top perfectly, but to avoid overstaying a mature bull cycle.
Cryptobirb also suggested that an altcoin season could emerge after Bitcoin reaches its peak, echoing a pattern seen in some earlier market phases where capital rotated outward once Bitcoin’s momentum began to slow. Even so, the analyst’s central point remains focused on Bitcoin: the current setup resembles the final innings of a historical cycle rather than the early stages of a fresh one.
As with all cycle-based models, the forecast relies on historical probabilities rather than certainty. Bitcoin’s market structure has evolved over time, and macro conditions, liquidity trends, and investor sentiment can all alter the path. Even so, the analysis reflects a widely followed idea in crypto markets: that halving events and long-cycle timing still matter, and that late 2025 may prove to be a decisive period for Bitcoin’s next major turning point.
