According to CoinDesk, Tuesdays have emerged as the most volatile day for bitcoin traders in 2025, with significant price fluctuations observed. Data from Amberdata reveals that realized volatility on Tuesdays has averaged 82 over the past month, marking it as a day of heightened market activity. Realized volatility is a measure of the standard deviation of returns from the market’s mean return, indicating past price movements. This contrasts with implied volatility, which reflects the market’s expectations for future price changes.
Amberdata's analysis extends to monthly volatility, highlighting March 2024 as the period with the highest volatility, recorded at 67. This trend is set against the backdrop of bitcoin's recent 30% decline from its all-time high, where its one-month annualized daily realized volatility approached 70, compared to an average of about 50. Historical data from Glassnode points to two other instances of similar volatility spikes: one in March 2024, following a surge to a record high of $73,000, and another in August 2024, during the yen carry trade unwind.
These fluctuations underscore the unpredictable nature of bitcoin trading, particularly on Tuesdays, and highlight the importance of understanding both realized and implied volatility for traders navigating the cryptocurrency market. As the market continues to evolve, traders remain vigilant, anticipating potential shifts in volatility patterns and preparing for the challenges and opportunities they present.
