To answer your question, I stated crypto trading in december 2017 (FML). I'm pretty cautious since i'm just beginning, but I watched all of your tutorials. I work full time as an economist, but I manage to trade or chek for opportunities of trading about 4-6 hours per day. One thing is for sure : since I started crypto trading, I sleep a lot less, but it's worth it. Keep up the good work and thanks.
