It seems the player with the best reputability and/or involvement in the Bitcoin development itself... Well, basically it seems that if an up and coming player in the market can prove themselves, then maybe they could swing the pendulum in their favor?
I dunno, but the fact of the matter is clear, that Intersango has seen some recent upward sales. Though now that they've capped off at that, it just seems fitting that possibly other big markets will see upward shifts? Anyone see where I'm getting at?
