So I realized there are so many things that can't be taught in trading.
One major thing I know can't be taught is the psychological aspect of trading.
No matter the number of videos you watch on this, you need to learn your psychology by Yourself!
Completely you're absolutely right because psychological is something that has to do with traders/investors' maturity status and this is the reason why some people believe crypto trading is not meant for people that can put their psychological in check.
What other things can't be taught in trading?
One of other that cant be taught is self control/decision making in terms of invest and panic.
