I do think, that in the future, XBY will begin trading on Trex. The necessary criteria is pretty much met. The team, I'm sure, has discussed this. Larger volume exchanges, like Bittrex, (I use Trex the most actually) makes it much easier to draw attention to the coin, the community, and the technology.
