In September 2025, Bitcoin encounters traditional seasonal weakness, yet the number of large holders reaches a record, prompting discussions about the potential implications of these factors on the market.
Seasonal Weakness and Bitcoin Price History
Historical data from 2010 to 2025 shows that September is the weakest month for Bitcoin (BTC). According to Bitwise Asset Management, the token posted an average decline of 4.68% each September during that period. Analysts link this pattern to recurring profit-taking and lower liquidity.
Whale Activity and Its Impact
In 2025, the number of addresses holding at least 100 BTC climbed to a record 19,130. This figure surpassed the previous high of 18,544 in 2017. Over the years, the growth of large holders has been steady. In 2010, there were only 1,375 such addresses. Whale activity is tracked because significant inflows often precede major price moves. However, the data does not guarantee short-term price direction.
Market Outlook
The market in September 2025 stood at a crossroads. Seasonal trends suggested weakness, but whale accumulation reached historic levels. These factors set the stage for possible volatility. Institutional interest, macroeconomic policy, and regulatory updates are likely to shape outcomes. Traders are monitoring whether whale buying will offset September's historical pattern of losses.
In September 2025, Bitcoin demonstrates usual seasonal weaknesses, yet the record activity of large holders could significantly impact the market. Expectations regarding future price movements remain the focal point for analysts.
