Svmuu reported that Greeks.live posted on the X platform, stating that today's Bitcoin call options trading volume reached nearly $850 million, accounting for over 35%, primarily driven by position rollovers. Influenced by the Middle East situation and U.S. stock market trends, this final week has seen significant volatility, but capitalizing on "doom-day" selling ahead of major expiry dates remains a high-probability trading strategy. It is understood that this Friday marks the quarterly expiry, with over 40% of options expiring, and the most concentrated strike price of $75,000 remains a strong resistance level.
