According to Wu Shuo, Greekslive revealed that 21,000 BTC options are about to expire, with a Put Call Ratio of 0.62, a maximum pain point of US$69,000, and a nominal value of US$1.5 billion. At the same time, 230,000 ETH options will also expire, with a Put Call Ratio of 0.49, a maximum pain point of $3,425, and a nominal value of $800 million. The level of volatility in the crypto market has increased significantly this week, with the battle for $70,000 and $3,500 fierce. However, there has been a significant decline in the IVs of each major period. Selling calls has been the most important transaction this month, and the halving expectation seems to have been overdrafted.
