Finding crypto coins is not easy to determined if it is good or shitcoins. In my way of finding good crypto coins, I first research what projects have a good coins and look at their websites and look also any information that can determined if that coins are good. Try to be active in all social media account so that you can get some idea on everything you need to know. You can also look at the furom in different signatures, find time to look in the project if it is promising in that way you can have idea which coins to invest.
