[Today's Bitcoin Block Call Options Trading Reaches Nearly $850 Million, Accounting for Over 35%] According to a report by Jinse Finance, data from Greeks.live shows that today's Bitcoin block call options trading reached nearly $850 million, accounting for over 35%, primarily driven by position transfers. Influenced by the Middle East situation and U.S. stock market trends, volatility has been significant in this final week. However, end-of-cycle sell-offs on major expiration days remain a high-probability trading strategy. It is reported that this Friday marks the quarterly expiration, with over 40% of options set to expire. Currently, the $75,000 level remains a strong resistance point.
