A total of 141,271 Bitcoin option contracts, worth over $14.0 billion, will expire on Deribit exchange this Friday, accounting for over 40% of the total open interest. 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 Business Development Asia at Deribit, said that nearly 20% of the expiring call options are in the money, indicating that call option buyers have performed well this cycle. The maximum pain point for this expiration is $102,000. The latest market fund flow is slightly 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 expiring on June 27. Prices are expected to fluctuate tightly before expiration, and implied volatility remains high. (CoinDesk) [Odaily Planet Daily]
