Foresight News reported that Matrixport tweeted, "Despite Trump once again raising tariff threats, the implied volatility of bitcoin and ethereum has only slightly increased. Since mid-November, overall implied volatility has actually declined significantly, with a cumulative decrease of about 18-25 volatility points over the past two months, indicating a notable compression. The performance of the options market shows weak momentum for chasing gains, and there has been no significant increase in demand for downside hedging. In this volatility environment, positions and options strategies are more focused on yield enhancement: on ethereum, some sophisticated investors are increasing their spot holdings while continuously selling call options to collect premiums. Although this strategy somewhat limits the upside potential, in a market with low leverage and prices fluctuating mostly within a range, it is more conducive to monetizing volatility, smoothing, and enhancing portfolio returns, which aligns well with the current market environment."
