Greeks.live stated that the volatility of cryptocurrencies has significantly decreased this week. Bitcoin touched $38,000 three times after last week's monthly settlement, but ultimately failed to hold its ground. Looking at option data, the put/call ratio is relatively low, indicating that this week's main trading is focused on call options, with the Maxpain point close to the strike price. As the upward trend becomes increasingly tepid, the skewness level of options gradually decreases. Fewer and fewer investors are bullish on short-term gains, with expectations of an increase mainly focused on the approval of ETFs in January.
