Everyone has experienced something like that, but there are some people who can go through it. if that happens to me, I will improve my trading plan, I will see the chart and the moving average price at that time. and looking for news about crypto. I am looking for momentum to buy, and determine at what price I should sell
The problem is such pump that happens after we sell is totally out of our control, you just can't know whether the coin will go beyond the price when you were selling or instead dumping and trading plan honestly have a very little to do with it except you want to spread your sell order across many price point then maybe that could minimize the risk of selling to early.
