I like VeChain. It's undervalued and could win the 'most promising coin' at the crypto oscars. However, it did have it's rise and it's not under the radar any longer. I would suggest looking into coins that may NOT change the world, but have a high chance of adoption.

Many of these coins are in the gaming industry, which I feel is more primed for adoption that most other industries. It is a community fit because:

1. The gaming community has already assigned real monetary value to virtual goods
2. It solves a major problem where a lot of fraud happens with the trading of gaming items/tokens

Off the top of my head, coins like Enjin and GTO come to mind. Of course, GTO being a recent call of Palm Beach.
