Fear . I think this is the problem most traders encounter. And my self is like that, the time when I first invested I lost a lot because of this. And now I have improved it.
what kind of fear do you mean?
because maybe someday I will enter the trade also later, therefore I also need to learn.
I think the fear in question is, fear of losing money used to trade, we all know that if the market price suddenly drops and does not rise again, all the money used to trade will just disappear, this is what traders fear.
You must try to trade, and be careful to make a profit.
