I can't follow as well. The project looks ok (can't see a special USP) and the team seems to be commited, but I'm missing the visionary part/use case. Therefore I assume he either knows the dev (and that they will deliver something special) or he knows that they will get onto another (less crappy) exchange which would increase the the demand. Nevertheless I bought some, did the same with XRB (which looked similar at the time) and turned out to be a good pick.
