Today's largest BTC options block trade: A major investor sold 500 BTC worth $114,000 call options expiring tomorrow, September 18th, earning approximately $1.7 million. 👉 The Federal Reserve FOMC interest rate decision will be held at 2:00 AM tomorrow (expected rate cut: 4.5% to 4.25%). Before major macroeconomic events, investors often close positions to hedge against risk. If there's no rate cut or if it signals economic concerns, the market could plummet. Betting on a "no significant rise" offers significant profit potential.
