Science popularization post: Selling a 4800 call option on ETH at the end of March can earn a premium (currency based) of 2.65% and an annualized rate of 24%. Expired price<; 4888 is profitable, and if the holding spot exceeds 4800 at maturity, it will be sold at a price of 4800. I am currently selling ETH call options aggressively, and if I really break through, I will sell spot money! I really want to sell, but the price doesn't give me a chance. 🥲
