Obviously it's a derivative thing, as BTG hasn't been "launched" yet, so people are straight up gambling right now with something that doesn't exist.  Yobit has done this before, and it's sketchy as hell, and I'm wondering if it's even legal.  No US exchange would probably get away with just creating a derivative security/currency out of thin air,  but this is Yobit.  Ny prediction is that they'll eventually get shut down by regulators.  I don't even know what country they're based out of.
