The dude is in net profit from trading, he only used a much higher leverage on that trade and somewhat got liquidated.
A Ric person like him suppose not use leverage at all which is the reason he lost so much. Using millions to trade can give high ROI but I do not know the reason he is using high leverage to trade which is just greediness and he got liquidated. If he is not careful, he may later go broke or he should just change.
