[Matrixport: Bitcoin's narrow fluctuations drive the selling option strategy, and volatility is expected to continue to decline] On September 24, Matrixport pointed out in its latest report: "Although Bitcoin is inherently volatile, the 30-day rolling return rate shows that its price has basically remained within a floating range of +20% in the past 18 months. We expect volatility to decline further, so we recommend the adoption of a selling option strategy in early 2023, including selling out-of-the-money put and call options, to obtain additional returns. Even though this strategy may incur losses, it still performs well overall as volatility declines overall. With the launch of Bitcoin ETF-related options, more institutional participants are expected to enter the market and further compress volatility. Therefore, selling volatility remains a viable strategy for Bitcoin holders to obtain additional returns."
