Bitcoin's September 2025 Performance Defies Historical Trends

According to Cointelegraph, Bitcoin (BTC) has achieved an impressive performance this September, marking its best showing since 2012. Historically, September has been a challenging month for Bitcoin, often referred to as "Rektember" due to its average losses of around 8%. However, this year, Bitcoin has defied these seasonal trends by posting an 8% gain, making it the second-best September in its history. The only time Bitcoin saw a more profitable September was in 2012, when it recorded a 19.8% increase. This year's performance is significant as it comes during a period of high stakes for Bitcoin's price seasonality. Historical patterns suggest that the next bull market peak is imminent, with other risk assets like gold and the S&P 500 also reaching new all-time highs. Despite these market dynamics, Bitcoin has managed to maintain its upward trajectory, even as its price volatility has reached levels rarely seen before. Data from CoinGlass and BiTBO confirms that Bitcoin's September 2025 upside is its second-best ever, highlighting an unusual bull market cycle. In 2025, Bitcoin's price volatility has decreased significantly, contrary to the expectations of many market participants who anticipated more fluctuations based on past performance. CoinGlass data indicates that volatility has dropped to levels not observed in over a decade, with a notable decline starting in April. Onchain analytics firm Glassnode also points out that the severity of Bitcoin's price drawdowns from all-time highs has been less pronounced this year, with the largest drawdown reaching only 30%, compared to previous cycles where drawdowns reached up to 80%. Despite the reduced volatility, Bitcoin's bull market performance has been noteworthy, although it struggles to match the intensity of previous cycles. In July, Cointelegraph reported on potential 50% price gains following unusually low readings from the Bitcoin Implied Volatility Index metric.
