Bitcoin’s September Weakness: Are Whales Buoying Prices Amidst Historical Trends?

Bitcoin is experiencing a historically weak September, with the token’s price dropping towards $109,000 in 2025. This comes as large holders saw record accumulation of Bitcoin at a time when seasonal weakness typically looms. While historical data suggests September has been the weakest month for BTC since 2010, analysts say these trends may be reversed by whale buying activity. The number of addresses holding at least 100 Bitcoin surged to a record high of 19,130 in 2025, surpassing the previous peak from 2017.
