One of the most marked reasons for this behavior is Seasonal effect: After the boreal summer, financial markets in general usually show weakness, with investors adjusting portfolios, taking profits or selling risk assets to face end of the year expenses and tax obligations. In addition, there is a Psychological bias: Many traders anticipate weakness and act accordingly, reinforcing the pattern. To this is added the least typical summer liquidity, which amplifies volatility and falls. They also influence Macroeconomic factors. September is usually a key month for central banks decisions, especially the Federal Reserve of the United States, whose meetings generate uncertainty in the markets. Given expectations of rates or restrictive policies, investors tend to reduce exposure to cryptoactive.

It is worth saying that it is impossible to anticipate the future with total certainty. But, what is certain, is that September 2025 will be a month of high volatility for bitcoin and cryptocurrencies. Therefore … to adjust the belts and enjoy the trip!
