More than $2.5 billion worth of cryptocurrency options, including $2.15 billion in Bitcoin and $408 million in Ethereum options, will expire this Friday. Bitcoin's max pain price is $82,000, with significant open interest concentrated between $80,000 and $90,000 strike prices, indicating a defensive investor sentiment amid volatility. After expiration, the influence of major strike price clusters on price action may diminish, potentially causing a shift in market dynamics.
