Information released by Deribit officials shows that in today's BTC bulk option trading, a user paid $3.617 million to sell call options with a strike price of 65,000 at the end of June, while buying call options with a strike price of $100,000 at the end of March next year, totaling 250 BTC.

According to the officials, this type of operation is a common strategy in the short-term bearish and long-term bullish outlook, using the premium received from selling options to lower the cost of buying forward options and hedge to reduce risk.
