Another thing is, at least be aware of your financial and emotional capability.
Those two often become the reasons for a traders' decline in ability to trade or the motivation to trade. Both are important even if they sound different. Lack of money to trade at the proper time can be disastrous specially when rapidly prices are fluctuating and you have been waiting for a long time for a proper entry price. Lack of emotional control can lead to wrong decisions.
If you're going to read and research, look for.actusl experiences of traders. Learn from other people's mistakes and learn from your own. You can't take away the fact that we all will make the same mistakes one way or another so you have to know what your contingencies are.
This is one tough thing to do. If you ask some trader they wont reveal their mistakes but give some generalized fallacies. Nobody wants to face their downfalls in reality. But they will try to pump their own shitcoins.
