According to TechFlow, Lin Chen, head of Deribit Asia Pacific, said that the largest BTC option today was sold by a user who earned a premium of 1.349 million US dollars and sold 65,000 call options at the end of September, totaling 685 BTC.
It is believed that the user holds a large amount of BTC spot, and then earns some income by selling call options. If the price is less than 67,000 at expiration, it will be profitable, and the currency-based income will reach 3.7% (about 28.73% annualized).
