The crypto market in the summer of 2025: will “Black September” return?

August 10, 2025blockchain

In the crypto community, September is known as a historically “tough” month. Bitcoin has performed negatively this month in 9 of the last 11 years. Is this also true in 2025?

The historical statistics

September is on average the worst performing month for Bitcoin. Average negative return of about 5-7%. On the other hand, October (“Uptober”) that follows is considered strong. November-December is even stronger in the Halving years.

What explains the phenomenon?

There is no unequivocal accepted explanation. One of the explanations: summer = positive sentiment and buying, September = actual profits before the end of the year. Psychological effects: self-anticipation of Black September can fulfill itself.

2025 in perspective

In the Elving years (2024), the summer-autumn trend was more positive. In 2025 – a year after the halving – history points to a bull market. Will the seasonal pattern overcome the halving cycle? This is not a recommended bet.

What to do?

Seasonality is a given, an uncertainty. Diversification, DCA (gradual investing), and not trying to time the market are basic tips. Read about macro analysis.
