I like the alt coins on Hive-Engine. Most Hive based alt coins supplement rewards on Hive.
As for alt-coins in the world at large, independent investors lack the full information needed to day trade the coins. So, it is a market that I would avoid.

I haven't honestly given too much time to the H-E alt coins as so many of them are so... static. Leo has had wonderful gains, but most of the other tokens that I've looked at have remained basically the same price they were a year ago. Maybe I'll give it a better look though in the future here.
