I agree with you if I comes from the perspective of investment. For trading, I have a trailing stop loss in place so that the min profits are protected when the there is a negative movement. I cast this rule in stone to avoid human emotion getting involved. Example, price move up by 40%, stoploss for me will be at 30% of the crypto price that I have purchased. If the crypto falls and touch my stoploss, I am out. I have no regrets even if the crypto raises for the next few days as taking profit is never wrong. I am preparing to exit from the following crypto. NEM: $30k invested, potential profits currently is around 90%. Trailing stoploss at around 80% profits. XRP: $350k invested, almost hitting 300% ROI. Trailing stoploss at 300% so that the profit can be protected but I expect this to go higher.
