The BTC volatility index rose to 75.84 yesterday, approaching its highest level in nearly a year

The BitVol index rose to 75.84 yesterday, a daily increase of 2.21%, close to the highest level in nearly a year (it reached 76.99 on March 19). Note: The BitVol index measures the expected implied volatility for the next 30 days derived from tradable Bitcoin option prices. Implied volatility refers to the volatility implied by actual option prices. It is calculated using the B-S option pricing formula, substituting all parameters except for volatility σ into the formula and then deducing it backwards. The actual price of an option is formed through competition among many options traders, therefore, implied volatility represents market participants' views and expectations about future markets and is considered as closest to real-time volatility at that time.
