Your talk actually makes a lot of sense, because overconfidence has really affected a lot people in this trading business, and yet they still don't want to accept any outcome in good faith. Normally, being confident is a very good thing, but it should be for something you are very sure will give you a good result in the end. For example, with something like Bitcoin investment, you can have a lot of confidence in Bitcoin because it is something that is almost certain to bring profit.
Exactly, building confidence is good ,that alone can help one achieve a certain milestone, imagine investing into Bitcoin and having over confidence that in years to come ,there will be massive profit ,that alone can keep your hope alive .
In trading is very difficult to achieve some level of profit ,so exercising overconfident in trading may not yard any profitable result ,losing your money is very easy when it comes to trading ,so over confidence to me is not applicable to trading .
