You will know when to sell your crypto investment when you think and calculate that you already have enough margin or profit from the investment. But this is also tricky and could be made you feel frustrated if the price is becoming higher than when you sold.
Events when we sell that according to a hunch will drop again or become a stable price, and in fact prices continue to rise and that is annoying and but that has become commonplace because prices are difficult to predict.
