币界网报道：According to data from Greeks.live analyst Adam, on June 27, 139,000 BTC options expired on June 27, with a Put Call Ratio of 0.75, a maximum pain point of $102,000, and a nominal value of $15 billion. 939,000 ETH options expired, with a Put Call Ratio of 0.52, a maximum pain point of $2,200, and a nominal value of $2.29 billion. The analyst said that today is the mid-year quarterly delivery, with more than $17 billion in options delivered, accounting for more than 30% of the current total positions. Because a large number of options expired, there were a lot of large bullish transactions in the past two days, and nearly $1.4 billion of public bullish transactions were traded in the past 24 hours, almost all of which were shifted. From the main options data, in terms of implied volatility, BTC's IV is still hovering at a low level, and the medium- and short-term IV is generally below 35%. ETH's IV has fallen slightly, but it is still as high as nearly 65%. The recent 30% IV difference has continued for several days, and there is a large space for volatility cross-currency strategy operations.
