I want to choose crypto currency trading as a career
Making trading as a career doesn't seem ideal because trading is not like a job where you will definitely get a salary when you finish the job.
In trading, you can not only get profits but losses will also be impossible for you to avoid, no matter how skilled you are at trading, you will definitely get both, so that when you are not mentally able to see the losses you get then you will be even more stressed and it will make it more difficult to analyze the market for opening positions in the next trade, so if you want to make trading a career then you must have income from other sources and the money you use to trade is what you can afford to lose, but I don't see that as an ideal thing to do as a career.
