I'm 90% sure that Nicesoft is a personal friend posing as just another player or alt account that belongs to Xiaoxiao. No smoking gun proof, but I'd be surprised if I were wrong (although I wouldn't feel bad considering the shit he's made up about me and pretended like they were fact)
Edit: I wouldn't normally make an accusation like this without evidence to prove it beyond a reasonable doubt. But I'm making an exception here because they have each proven themselves to be total scum and It would just make perfect sense if the nicesoft account were created with the sole purpose of promoting Betcoin and more specifically Xiaoxiao as an affiliate if you look at the post history (including those posts complaining about late rake-back payments - and the swc affiliate link included in sig)
