Bitcoin has had one of the best Septembers in history, confirming that 2025 is an exceptional year for cryptocurrencies. According to data from CoinGlass and BiTBO, the price of Bitcoin rose by 8 percent in September, making it the second-best performance for the ninth month in history—only 2012 was better, when the price jumped by almost 20 percent.
This is interesting news for ordinary investors, as September is usually a weaker month for Bitcoin.The current growth suggests that the market is exceptionally strong this year and has entered a so-called “bull” phase, where prices are rising over the long term. Moreover, historical data shows that such periods often precede further strengthening and may even pave the way for new price records.
Bitcoin is growing more steadily than before
The key difference from previous years is how steadily the price is developing. Bitcoin is known for its volatility, with sharp ups and downs. This time, however, the market is much more stable. This year’s biggest drop from its peak was only 30 percent, while in previous years, drops of up to 80 percent were not uncommon. According to CoinGlass data, Bitcoin’s volatility is at its lowest in more than a decade.
This stability has two effects: investors experience less stress, but at the same time, growth is slower than in previous “wilder” cycles. However, according to on-chain analytics company Glassnode, this is still an unusual year that is rewriting historical patterns of behavior in the cryptocurrency market.
What may come next
Some analysts point out that periods of low volatility often precede larger market movements. This could mean further growth and, according to some estimates, the possibility that the price of Bitcoin will approach new highs in the coming months. On the other hand, even a calm market can change quickly, and investors should also consider the possibility of a correction.
In any case, September 2025 is already going down in Bitcoin history as the second best month in its entire existence, confirming that the current bull market has a different pace and momentum than previous ones.
