According to Crypto Rover, $3 billion worth of Bitcoin and Ethereum options are expiring today, a significant event that often leads to increased volatility and trading volume in the crypto market. Traders should monitor price action closely as large options expiries can trigger sharp movements and liquidity shifts, particularly for BTC and ETH pairs. This event may present both risk and opportunity for short-term trading strategies, as market makers and institutional participants adjust positions in response to expiring contracts (source: Crypto Rover via Twitter, May 9, 2025).
