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.
People need to understand that they cannot rely on something which doesn’t have a guaranteed and fixed income. Trading is very uncertain. Sometimes you make huge profits, but majority time you don’t make profits, rather you make losses. Hence making it as your primary source of income and treating it as professional can be really risky. What you can do is rather do a small job for daily necessities and do trading as a side income. This is the best way to make money both ways.
