It's really hard to say, in the long-game. Because it's so new, it's highly speculative.
From what I'm seeing on the platform, they're doing all the things that Steemit should have been working on two years ago. I've interacted a bit with the founder and am impressed.
They want to monetize every angle, but also don't want to over-monetize (to the point of chasing people off). You can see that reflected in polls they take regularly. It also reflects that they're sensitive to what their customer base wants to do.
It's not it's own blockchain, like Steem is. That may give Steem an edge, along with an already great community and first mover advantage. But EOSio has massive momentum. Even Ethereum didn't have this sort of momentum at this stage, and look how well it's done. Trybe, being built on EOSio, gets to ride that and is the first mover on the EOSio blockchain. That'll mean something.
Their roadmap already has a lot of the things folks are just now talking about for Steem. They're working on an API, integration with other sites, subsites, groups, subscription services, etc. They have their own wallet and are looking at exchange options, as well as a portfolio tracker.
So, what do you think? We've taken a position in it.
Incidentally, we're working on the ability to post directly to Trybe from Scripsio. It won't be easy, but hopefully we can pull it off so that you could post to both Steem and Trybe simultaneously from Scripsio. It'll be interesting to see how this plays out. But I'd encourage anyone to get started on Trybe now. If it doesn't work out, well, it's not the first time. If it does, you might do nicely just like the earliest adopters (first couple of months) of Steem did. Trybe is Trybe.one.
