2. Xiaoxiao is a big affliate there, and he has profited over 100 btc(just my speculation) I think xiaoxiao earned enough, so he locked his thread. Xiaoxiao didn't lose anything, he ahs hundreds of downlines can earn very decent money per month.
He locked the thread, so others can not post anymore and warn potential victims. But he is still posting in his thread and try to draw new customers in...
Maybe double xiao fear others complain in his OP? He often spams and self-bumps his thread. Damn he is a greedy affiliate
