Traders use historical volatility to estimate future volatility. In crypto, this doesn't work. Volatility changes significantly and rapidly. Yesterday's vol tells you little about tomorrow.
Hypothesis HY10031
Traders use historical volatility to estimate future volatility. In crypto, this doesn't work. Volatility changes significantly and rapidly. Yesterday's vol tells you little about tomorrow.
Trading hypothesis
What traders get wrong
False assumption:
"Historical volatility predicts future volatility."
Truth:
In crypto, volatility changes significantly and rapidly. Historical vol has low predictive power.
Problem for trader:
Vol-of-vol is extreme. Regime changes are sudden. Your volatility estimates are wrong.
Key takeaways
What you should consider as a trader
- Vol-of-vol is extreme - Volatility of volatility is 3-5x higher than equities.
- Regime changes are sudden - Vol can double overnight with no warning.
- Short lookback is useless - 30-day vol tells you little about next 30 days.
- Long lookback is also useless - Conditions change too fast.
- Implied vol often undershoots - Realized frequently exceeds implied.

Science behind hypothesis
Research supports this hypothesis
Research shows historical vol explains less than 30% of future vol variance in crypto.
Bottom line
Yesterday's volatility is a poor guide to tomorrow's. Real-time vol regime detection helps you adapt before your risk models break. Madjik's volatility regime indicators signal when vol is about to spike or collapse, not after it already has.
Practical use
How to use this data in trading:
Combine these metrics for comprehensive analysis:
- ME10013 (Volatility & Risk): Trade IV-RV spreads, size positions using VaR, and select strategies based on volatility regime.
- ME10016 (Regime Detection): Select appropriate strategies (trend, mean reversion, volatility) based on detected market regime.
