The cryptocurrency market has similar characteristics to the futures market, and trend-following strategies are attractive in this market. This paper uses the spot price data of Bitcoin against the US dollar from January 1, 2013 to September 27, 2023, as well as the daily data of the S & P 500 index and the Shanghai and Shenzhen 300 index in the same period. A trend-following strategy is used to evaluate indicators such as return, Sharpe ratio, Sortino ratio, risk exposure and maximum drawback by optimizing parameters. By analyzing ten years of data on Bitcoin, the research revealed the potential return on investment of the cryptocurrency trend-following strategy, which achieved an annualized return of 112.7%. The results show that the trend tracking strategy of digital currency is more significant under the special conditions of increasing market volatility. Bitcoin shows potential value in investment portfolios, especially when market volatility increases and may become a hedging tool and provide more diversified investment strategies.
