As long as you know what you are doing there isn't much difference. As long as you make money, it means your strategy works fine. I don't like to trade forex because I don't understand it. I can't come up with an educated guess no matter what strategy I follow. Trading bitcoin is easy. Buy buy buy till your stash gets big, and sell some when the price hits a new ATH. It is a no brainer strategy which you can't do with forex. I know some people make big money from forex trading but it is not my thing. Everybody should stick with what they understand best and it is crypto for me.
