panic sell in trading this always happen not just in crypto but on every investment instrument that I know including stock and even a mutual fund, I know that one people and the other had different risk but if you hold a good coin like bitcoin or blue chip stock like apple you can wait for some moment or do DCA and in the long run is still gonna profitable
Everything related to this instrument will definitely happen the same thing, the only difference is the product invested. However, this will only be felt by new people in a space like this, while old people or people who are experienced will tend to be more relaxed and will not do anything rash and sell panic. Even in the worst case, when a coin dies for some reason, investors remain calm. Losses and regrets must be there because it is natural as a human being. However, they are more prepared, because they planned it very well from the start, so they still have money in other assets.
