Who could the forkers be? Bitmain or some opponent? The temporary bump in price may look good for Bitmain's books with IPO investors, but I think consensus is that the steady post-fork value will take a dent. This makes it less likely that it is a Bitmain tactic. But are there any real opponents in that camp?

edit of course it's just a media circus to dilute coins, pump prices and be a nuisance to the real bitcoin. they all suck each other in private.
