If I have to start with you to learn how to trade in crypto currency. but always be careful about scams because they do not lose my advice before investing. You need to read the white paper to find out about the project. so you will not fall victim to a scam.
Well, I would not consider cryptotrading as a profession, because this environment is out of the law and rules. As a rule, greed leads to crypto trading, but not many survive and most lose their money. But again it's up to you to make decision here.
