Bitcoin is experiencing extreme price swings more frequently in 2026 than in 2018, even as its annualized volatility has dropped to 46% from 84% eight years ago. While average daily moves have stabilized due to institutional adoption and ETF liquidity, the asset continues to register outsized 3-sigma events that defy standard distribution models. Since 2024, Bitcoin has recorded 26 three-sigma trading days compared to just eight for Nvidia, 16 for the S&P 500, and 12 for gold. Although the magnitude of these extreme moves has decreased to roughly 7% from 10% in 2018, their persistence highlights ongoing risks from macro factors, leverage, and positioning that challenge volatility-based risk management strategies.
