Here is my system for my friends. You scour coins that are going up currently (the trick) and you make sure you buy only if you can, in all probability, get out if a minimal loss if things go south (the most important part). You basically just try to make 1-10% on a trade, and don't take more than a 2% loss if possible.
I bought in markets that stood still and one slightly dipped today. So fees + small loss.
Not going to make you rich right away.
