An investor bought a $3000 ETH call option at the end of March and sold a $4000 call option for the same period

According to Lin Chen, the head of Deribit's Asia Pacific business, an investor purchased a $3000 ETH call option at the end of March and sold a $4000 call option for the same period, with a total of 3500 ETH on one side and a premium of $382000 paid. Analysis suggests that this transaction is a reduction in position, which means closing the previous bear market call option spread. Recently, there has been a sharp drop in IV volatility, and short selling volatility to take profits.
