Analysis: Bitcoin's historic decline in September may have been digested by the market

According to CoinDesk, historical data shows that Bitcoin may have bottomed out on September 1, 2025, with the low of about $107,000 on that month. Since July 2024, Bitcoin has often formed the low point of the month in the first 10 days of each month. Although February, June and August 2025 are exceptions and the low point appears late, the market also experienced a pullback in the first 10 days before the trend resumes. It is speculated that it may be related to the rebalancing of institutional portfolios and the concentration of key macroeconomic events at the beginning of the month. Oliver Knight, deputy editor-in-chief of CoinDesk Data and Tokens, said that multiple futures and options markets expire at the end of each month or early next month, which may trigger short-term volatility and cause trading activity to be sluggish because traders will choose to roll out or re-layout. Although historical performance cannot ensure the future, the fourth quarter has always been the strongest period of Bitcoin, with an average return of 85%, especially outstanding in October, and only two months since 2013.
