Bitcoin and the Monthly Bottom Pattern: Has September 2025 Established the Lowest Zone?

Historical data shows that Bitcoin may have established a bottom for September 2025 around the zone of 107,000 USD on September 1. Looking back from July 2024 to now, a relatively consistent pattern has emerged: Bitcoin often sets the monthly bottom within the first 10 days. 🔎 Rare exceptions occur in February, June, and August 2025, when the lowest levels appear later in the month. However, even in those cases, the market still witnesses a significant correction in the first 10 days before continuing the major trend. 📌 Possible Causes? One hypothesis is that this is related to the portfolio rebalancing activities of large institutions or the coincidence with important macroeconomic events that often occur at the beginning of the month. Oliver Knight, Deputy Editor of Data and Token at CoinDesk, shared: "It is important to note that many futures and options contracts typically expire on the last day of the month or the first day of the following month. This can lead to short-term volatility, after which the market often settles down as traders close positions, shift their positions, or restructure their portfolios." 📈 Signal for Q4 Although the past does not guarantee the future, as we enter the last quarter of the year, it should be emphasized that Q4 has always been the strongest quarter in Bitcoin's history, with an average profit of 85%. In particular, October stands out: since 2013, there have only been 2 instances where Bitcoin recorded a loss in this month. 👉 This means that if the pattern continues to repeat, the market may have already passed the bottom of September, paving the way for a booming Q4 and even a brilliant October.
