One of the largest BTC block options today is that a certain boss sold a call and put option for 80000 at the end of May, totaling 300 BTC, with a total income of about 250000 US dollars. The profit range upon expiration (at the end of May) is 69000 to 96000 yuan, and the maximum profit point is the BTC expiration price of 80000 yuan, with a profit of 16% on the coin base. The profit margin is very high. 🤑
