Though it might make for a good conspiracy, a 51% attack would be counterproductive to who ever is attempting it. It could cause all other holders to dump their coins and you being holder of about half of it would suffer with them. And what would you rule after this, ashes?
A state funded chinese miners attack to push the BU agenda is being FUDded by the nasty Jihan guy on twitter. Of course it will be another failure and then BUcoin can finally join XTcoin and Classiccoin altcoin cemetery.
