That problem is that people aren't much prepared for it (volatility) instead, they always think that the market price will always be moving high without suffering dumps on the way. If they anticipate this sort of challenge, they could surely adopt the system and most likely they could manage to keep their trust tightly. But that makes no sense at all when we are an impatient person and easily get into FOMO once the market fall.
Well most of new traders are like that, and we cannot really blame them because they are just starting to learn, what's wrong with it is that if they will continue to become noobs all the time that they are not learning on it, all of our experience should be always charge to experience. Doing full time trading maybe boring but if that what will change your life, why not?
