I believe you should not sell until it pump. Hold it and surely there will be a time it will increase for me that prevents me to have losses in my trading. HOLD IT!
There is no way that you could do Trading without losing any profits. Trading is an unpredictable job because of the prices of the tokens, you don't know when they are going to PUMP and DUMP, it is all about analyzation and prediction, that is why you can't say that there is a way to Trade without experiencing any loss at all, it is impossible.
