Lin Chen, head of Asia Pacific commerce at Deribit, wrote on the X platform that the largest bulk option in ETH today was that a user sold $3,400 of call and put options at the end of October, a total of 500 ETH, and received $394,000. The analysis believes that the investor shorts the volatility, the price profit range is $2750-4450, and the currency standard return is 24.45%. Maybe the investor thinks that the price will fluctuate repeatedly in this range.
