I want to choose crypto currency trading as a career but I feel like I need to know a lot about it to choose it as a career and I don't think there is anything better to do from here.
As I am new to this place I am trying to know which aspects I can take Cryptocurrency trading as my career if I know well.
Do not take trading as a career. It will not be helpful. Have something else that is your primary source of income and begin trading with small amount of money that you can afford to lose. See trading as gambling, although it is not gambling but it is as risky as gambling.
I totally agree with your takeaway. Trading is not a career, so it is very wrong to think of it as a career. However, to become a professional trader, it is possible that if you study all the points you share seriously, you will be successful in trading.
In essence, when trading, treat trading like a lover, wife, or child. When you lose or accept a loss, assume that you are being given a risk. So there won't be any emotions. Because it is true that trading strategy is only 20%, the rest must have a strong mentality in dealing with defeat and a good mentality for recovery. And his usual mentality had formed like that of a gambler. You will get used to taking risks. Take the mental side of the gambler, then you will become a strong and professional trader.
