According to Foresight News, the latest chart released by Matrixport shows that although Bitcoin is naturally volatile, the 30-day rolling return rate shows that its price has basically remained within a 20% floating range in the past 18 months. Matrixport expects volatility to decrease further, so it recommends a selling option strategy in early 2023, including selling out-of-the-money put and call options, to obtain additional income. 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, further compressing volatility. Therefore, selling volatility is still a viable strategy for Bitcoin holders to obtain additional income.
