According to CoinDesk, a total of 141,271 Bitcoin option contracts, worth over $14 billion and accounting for over 40% of the total open interest, will expire on Deribit exchange this Friday. Among them, 81,994 are call options, and the rest are put options. The current Bitcoin put-call ratio has risen to 0.72, partly driven by the "cash-secured put" strategy. Lin Chen, Head of Asia Business Development at Deribit, said that nearly 20% of the expiring call options are in the money, indicating that call option buyers have performed well this week. The maximum pain point for this expiration is $102,000. The latest market fund flow is skewed towards neutral, with traders selling straddles and selling call options with a strike price of approximately $105,000 and shorting put options with a strike price of $100,000 upon expiration on June 27. Price fluctuations are expected to tighten before expiration, and implied volatility remains high. [ChainCatcher]
