For sophisticated market observers, this September’s movements in Bitcoin have been less an alarm and more a familiar refrain—and, if history is any indication, savvy participants may already be eyeing greener Q4 pastures.
Bitcoin’s Seasonal Cyclicality Repeats
Since July 2024, Bitcoin has exhibited a distinct pattern: monthly lows typically materialize within the first 10 days of each month. Despite a few deviations (notably February, June, and August 2025), this rhythm has given analysts and portfolio managers a probabilistic edge in both timing and risk management.
Recently, Bitcoin found its September 2025 floor around $107,000 on the very first day of the month. Market speculation suggests this early-month malaise is shaped by a cocktail of institutional rebalancing and the clustering of key macroeconomic events–including the expiry of futures and options, which stirs volatility and settles positions just as a new month begins.

Supporting this thesis, Oliver Knight, Deputy Managing Editor for Data & Tokens at CoinDesk, emphasizes, “Several futures and options markets expire on the final day of the month or the first day of the next. This can lead to short-term volatility and a subsequent lull in trading activity as traders rollover trades or reposition entirely.” For fund managers, such recurring windows are more than interesting—they’re actionable.
Q4: Bitcoin’s Power Quarter
Of course, no market playbook is fail-safe. Yet the consensus among digital asset managers remains bullish, with Q4’s historic performance lending further optimism. On average, Bitcoin has surged an astounding 85% in Q4s, and since 2013, October has posted negative returns only twice. While past performance never guarantees future results, the data-driven argument is compelling for allocators seeking seasonal upside.
Macro Drivers and Behavioral Alpha
The inference: bitcoin’s recent downturn may not be a canary in the coal mine, but simply another cyclical opportunity—especially for fintech desks looking to optimize quarter-end rebalancing and risk exposure ahead of anticipated Q4 momentum.
Looking ahead, professional crypto investors and institutional desks would do well to overlay these behavioral patterns onto macroeconomic news flows and product expiry calendars. For those who do, the autumn could bring more treat than trick.
