This is not just another copycoin project, far more ambitious and rooted in principal not profit.
It's unfortunate perhaps there are not more markets but most in the know are holding and there's little added value from the pump and dump crowd. Investors looking for real projects can see what this is clearly enough.

Also for the more tech savvy watch the Github for signs of just how alive.. though that repository does not include all the devs background it's a good starting point.
