CoinVoice recently learned that Greeks.live researcher Adam posted on the social platform:

11,000 options expired, with a Put Call Ratio of 0.78, a maximum pain point of $64,000, and a notional value of $1.26 billion; 138,000 Ethereum options expired, with a Put Call Ratio of 0.61, a maximum pain point of $2,500, and a notional value of $360 million.

Bitcoin rebounded significantly this week, while Ethereum's rebound was relatively weak. The open interest of Ethereum options expiring this week was less than 30% of that of Bitcoin. From the perspective of implied volatility, the IV of ETH's at-the-money options around one month is only 4% higher than that of BTC, and it is still falling. [Original link]
