People do many things in crypto because of FOMO (Fear Of Missing Out). When they see the price is going up, they think you just miss this move, so quickly take entry in the market. Then the price goes down and they lose money.
It is better to stop doing anything due to FOMO. You can set your strategy, stay calm and follow it. If you miss something, you will look for another opportunity. You don't try to catch that and make a bad investment decision.
