Odaily Planet Daily News Lin Chen, head of Asia Pacific business at Deribit, wrote on X that today's largest BTC option: a user earned 153,000 in premiums, bought a 50,000 put option at the end of September + sold a 45,000 put option at the end of the year, a total of 100 BTC. The user used the premiums from selling put options to subsidize the cost of buying in September. He believes that the price may fall below 50,000 by the end of September, and if the price falls below 45,000 by the end of the year, he is willing to buy BTC at that price.
