According to Wu, Greekslive pointed out that despite the continued decline of Bitcoin and the spread of panic in the market, there are few put option transactions in the options market, and the main transactions are all call options. Especially for ETH, today's call option transactions accounted for 90% of the total transactions, which is a very rare extreme proportion. Transactions are scattered at the main term price levels this month, and the transactions are very scattered, and no large transactions are made. Observing the transactions should be the fluctuations before and after the halving.
