In the cryptocurrency market, stop-loss strategies are an essential "umbrella" for investors. Recently, Bitcoin prices have approached key levels, and the market is experiencing intense long-short competition and increased volatility. Investors can set a fixed percentage for stop-loss, such as decisively exiting if losses reach 10% of the principal. They can also refer to market volatility indicators, like the Average True Range (ATR), to scientifically set stop-loss levels, and can adopt trailing stops to lock in profits.
