I think the key to finding the coins that will stick around is to look at the tech behind them.

DragonChain is super promising. It was a blockchain platform developed by Disney and they have some really exciting tech. Their ICO is coming up really soon I think.

IOTA is great too https://iota.org/

and Komodo just announced some pretty impressive advancements. Unfortunately for them the quality of their announcement was so terrible that everyone freaked out, so now they have to work doubly hard to get people to pay attention to the pretty groundbreaking stuff they have been working on.
