Although forextrading and cryptocurrency trading are both profitable, I would personally say that cryptocurrency trading is the most profitable. Crypto currency trading seems to be the most profitable for me because I have proper knowledge about cryptocurrency trading and I have been able to earn by trading from here. And I haven't gained any experience about forex trading till date and I haven't done any trading there. I don't even know what forex trading is, that's why I don't think forex trading is profitable.
