What often makes many people lose money in crypto is not just panic, but when they feel the profits are still lacking and always lacking. For example, when Bitcoin goes up 5%, instead of selling, they keep waiting and even buy additional Bitcoin. In fact, by selling, the profits obtained are very good. Don't let greed make you lose in the end. So, when you get news that Bitcoin is going up and your investment is already profitable, don't hesitate to take advantage.
Panic is a big problem in trading and investing. If we get carried away by large market movement and fall into a panic that we will just start selling at any price possible. Critical and rational thinking is going to stop and we are just following the masses. This probably the worst thing we could do at that moment.
