Hard to go wrong with those four, I think. I'm going to be watching community coins pretty carefully going forward, whether it be HiveEngine or something else. LEO frankly surprised me, and I'm thinking that sort of community will drive Hive in the future.
I know what I think but not what I know
I think Leo surprised a lot of people. Even the ones that were smart enough to buy in when it was cheap. It is a good community and they have some great stuff in place to help you grow your stake.
I really do think LEO is the beacon for every other community to follow. You and I have seen a few come and go, and it looks to me like Leo is a big time keeper.
