I often use a strategy that combines fixed stop-loss and trailing stop-loss. Fixed stop-loss is set according to risk tolerance (e.g., a 5%-8% drop in position), anchoring at key support levels or round numbers to clearly define risk boundaries; trailing stop-loss moves up the profit-taking level as the market progresses, locking in profits while avoiding an early exit. When setting, I consider position size and target returns, ensuring that a single stop-loss loss does not exceed 2% of total capital, and that the risk-reward ratio is ≥1:2. I once exited before a certain altcoin's sharp decline with a 6% stop-loss, avoiding a 30% deep loss; disciplined stop-loss makes risk controllable and prevents emotional interference with decision-making. #止损策略
