Odaily News Stimulated by the price of Bitcoin breaking through $72,000, the options market's trading volume hit a one-month high today, with a total of more than $1 billion in cumulative block trades. Among them, the call option trading volume was about $700 million, and the put option trading volume was about $300 million. It is worth noting that a proportional spread strategy transaction: a large investor sold 250 call options with a strike price of $75,000 and bought 500 call options with a strike price of $90,000, indicating that it expected Bitcoin to either not reach a new high or quickly hit $100,000 once it broke through. This trading strategy saved about $13,000 in slippage through block trading, showing a bold and sophisticated market layout.
