To confirm whether this pessimistic sentiment exists only in the futures market, let's take a look at the situation in the options market. In options trading, there is a skewness indicator that can reflect market sentiment. When traders are worried about a significant price drop, they buy a large amount of put options, causing the price of put options to rise, and the skewness indicator will be above 5%; when the market is very bullish, the indicator will drop below -5%. $BTC
