Odaily Planet Daily News Matrixport released a chart saying that a year ago, we predicted that Bitcoin's volatility would remain between +/-20% in any 30-day rolling period, meaning that it was less likely to rebound or fall sharply. This provides option sellers with the opportunity to obtain additional premiums, thereby increasing Bitcoin's yield. The strategy suffered only minor temporary losses in two short periods at the end of the third quarter of 2023 and the first quarter of 2024. With the launch of the Bitcoin spot ETF, volatility is expected to decrease further, making option selling an effective profit strategy in the coming months.
