BlockBeats news, on March 21, the BitVol (Bitcoin Volatility) Index launched by the financial index company T3 Index in conjunction with the Bitcoin options trading platform LedgerX rose to 83.66 yesterday, close to the highest level of 87 in a year. BlockBeats Note: The BitVol Index measures 30-day expected implied volatility derived from tradable Bitcoin options prices. Implied volatility refers to the volatility implied by the actual option price. It uses the B-S option pricing formula to derive the volatility by substituting the actual price of the option and other parameters except volatility σ into the formula. The actual price of options is formed by competition among many option traders. Therefore, implied volatility represents market participants’ views and expectations for the future of the market, and is therefore considered to be closest to the true volatility at that time.
