In the cryptocurrency market, high volatility means both high returns and high risks coexist. Without a clear stop-loss strategy, greed in the moment can often lead to huge losses. Whether in spot or futures trading, setting stop-loss points is the core method to protect your capital and control risks. Don't wait until losses widen to regret not having set a stop-loss, and don't entertain the hope that 'it will bounce back.' A reasonable stop-loss can not only help you stay rational but also give you the opportunity to re-enter when the next market comes. Remember, protecting your capital should always come first. Develop a stop-loss strategy, starting now!
