Greeks live said that the ETH ETF will be launched next Tuesday. Stimulated by the good news, ETH rose by 8%, driving the entire crypto market to rise significantly. The sharp rise in currency prices has driven the IV of each term to rise simultaneously. The implied volatility of BTC has even increased more than that of ETH, but both are still at relatively low levels. Today, there are multiple doomsday call options that have increased by more than 1,000%, and the main transactions throughout the day are mainly active buying of call options, accounting for more than half of the trading volume.
