BTC fell below 67,000, what happened? It should be said that the positives have not been completely exhausted? I looked and found that there are options about to expire, and the pain point is at 67,000, so don't panic. I see that some big guys have also spoken, saying that ETH bullish sentiment is still strong. Greeks.live posted on the X platform that 21,000 BTC options are about to expire, with a put-call ratio of 0.88, a maximum pain point of $67,000, and a notional value of $1.4 billion. 350,000 ETH options are about to expire, with a put-call ratio of 0.58, a maximum pain point of $3,200, and a notional value of $1.3 billion. ETH took over the BTC rally, and encouraged by the progress of ETFs, it rose 20% in a single day, and the short-term option IV once reached 150%, which is much higher than the current IV of BTC in the same period. Now the divergence between BTC and ETH is obvious. Judging from the market trading and market trading structure, ETH's bullish sentiment is still strong, but it is difficult to maintain high IV in major terms. Calendar spreads will be a better choice. On the contrary, BTC is more balanced between long and short, and the power of selling call options is stronger.
