Bitcoin and Ether options with a combined notional value of $2.95 billion are set to expire on October 2, marking the first weekly settlement following the quarterly cycle. The expiry includes 30,500 Bitcoin options worth $2.63 billion and 116,000 Ethereum options valued at $320 million. Bitcoin's put-to-call ratio stands at 1.07 and its max pain price is $82,000, while Ethereum's ratio is 1.17 and its max pain level is $2,660. Bitcoin had rebounded after consolidating near $85,000 for more than a week, while call-option block trading remained active. Implied volatility across major maturities fell to cycle lows from the previous week, and gamma exposure was concentrated at $90,000 and above after a month-long advance.
