Bitcoin News Today: Bitcoin Bull Cycle Expected to Peak in October 2025 According to 35-Month Cycle Model

Cryptocurrency analyst Colin Talks Crypto has predicted that the current bull cycle for Bitcoin is likely to reach its peak in October 2025. This forecast is based on a re-evaluation of historical bull cycles, which he examined using two distinct measurement methods. According to Colin, the more consistent of the two is “Measurement B,” which averages a cycle duration of 35 months from bear-market lows to highs [1]. This pattern has shown consistency across past cycles and, if repeated, would point to late 2025 as the apex of the current cycle [4].

The analyst noted that the second cycle could be interpreted as either 28 or 35 months due to its “double-bottom” structure, while the third cycle was definitively 35 months long. Based on this data, Colin emphasized that the key takeaway is not a prediction of price levels but the observation of a cyclical pattern in market behavior [1].

Other analysts have also weighed in, with Peter Brandt estimating a 30% chance that Bitcoin has already reached its peak this cycle. However, he also proposed a potential peak around December 22, 2025, using a 37-month cycle model [3]. Meanwhile, a model from Bitcoin Intelligence and 21st Capital suggested a potential price rally to between $125,000 and $131,000 by late 2025, driven by favorable macroeconomic conditions and Bitcoin’s cyclical behavior [6].

Despite differing viewpoints on the exact timing, most models agree that the second half of 2025 will be a critical period for the cycle’s conclusion. Analysts caution that while timing may follow a predictable rhythm, the actual price peak remains subject to external factors such as regulatory changes, macroeconomic shifts, and liquidity events [4]. They also note that diminishing returns are observed with each cycle, making strategic positioning increasingly important as the cycle nears its end [4].

For investors, the fourth quarter of 2025 will be pivotal. As the market approaches its expected peak, volatility is expected to rise, and the potential for reduced returns from the cycle should be factored into investment decisions [4]. Analysts emphasize that these models should be used in conjunction with broader indicators, including on-chain metrics and macroeconomic data, to refine strategies for market entry and exit [4].

While the forecasts do not specify exact price levels, they provide a structural timeline for monitoring Bitcoin’s trajectory. As the October and December 2025 dates gain traction, attention is shifting from price tracking to broader implications for institutional flows and market structure [10].
