In my opinion, the best time to sell is when the market price of the coin is 20%+ higher than the market price at which you bought the coin. Dont wait till the market price is 95%+ before you sell. That only happens when you got your eyes glues to your machine 24/7. Dont be greedy... Make a little profit and grow it over time. Cryptomarket is growing and full of terror! Be careful
Every traders have own strategies to how they profile will grow some of them is like what you mentioned. But we all know that greedy people will not gone in trading there still greedy. If we teach our self to make a limit and not be so greedy I think we will be to what we have. In trading you can change that there's a greedy people..
