Yes, I do, even I do trade in my class! Because you never know when the price will go up suddenly! If the price goes down, I trade to convert into USDT or sell, even two days ago, I did a trade in my Parasitology class, lol!  It's all about you. If you can manage your works with the trade then do it. But it can not help you most of the time, because trade needs passion and attention!
