Analysis: Bitcoin has already seen 10 instances this year 3-sigma extreme volatility, more than 2018 the entire year
PANews October 10 reported, citing CoinDesk analysis, that Bitcoin 2026 has seen 10“3-sigma” extreme-volatility days so far this year (daily gains or losses exceeding 30 three times the -day realized volatility), exceeding 2018’s full-year total of 8 instances; however, this year’s annualized volatility is approximately 46%—far below approximately 2018 in 84%; the average magnitude of extreme volatility also fell from approximately 10%to approximately 7%. Since 2024, Bitcoin has recorded 3-sigma volatility days, reaching 26 instances, higher than Nvidia, the S&P 500 and gold.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
“3 sigma” can be understood as a daily gain or loss that is highly abnormal relative to recent volatility levels. The data indicate that these abnormal moves occurred more frequently, but this year’s overall volatility and average magnitude per extreme move were both lower than in 2018. It describes volatility characteristics only and does not indicate whether the price will rise or fall.
Why it matters to readers
An increase in extreme-volatility days means that abnormal price gains or losses have occurred more frequently in the short term, so participants may need to pay closer attention to price volatility and risk management. However, the lower annualized volatility and average extreme-move magnitude indicate that this year’s overall and per-event volatility intensity is lower than in 2018.
Beginners should note that an increase in the number of extreme-volatility events does not mean that Bitcoin must rise or fall; volatility frequency, volatility magnitude, and price direction are different concepts.
Risks and unknowns
The original text only relays CoinDesk analysis and does not provide the complete analysis, so the calculation process and data sources cannot be verified.
30 The specific calculation method and statistical sample for -day realized volatility are not stated.
The data cannot be used to determine Bitcoin’s subsequent price direction.
Nvidia, the S&P 500 and gold lack specific comparative figures.
