CoinVoice has recently learned that on October 3, the BitVol (Bitcoin volatility) index launched by financial index company T3 Index and Bitcoin options trading platform LedgerX rebounded to 42.53 yesterday, a daily increase of 10.24%.

CoinVoice Note: The BitVol index measures the 30-day expected implied volatility derived from the price of tradable Bitcoin options. Implied volatility refers to the volatility implied by the actual option price. It is the volatility inferred by substituting the actual option price and other parameters except volatility σ into the B-S option pricing formula.

The actual price of an option is formed by the competition of many option traders. Therefore, the implied volatility represents the market participants' views and expectations on the future of the market and is therefore considered to be the closest to the actual volatility at that time.
