Hi, im planing on ordering some antminer s9 from bitmain.com but I have read some very negative reviews and complains about bitmain. So what i heard is people been having issue ordering their antminer, the status for the order dont change from unpaid to paid after they have sent bitmain the money. Anyone has experience with bitmain before, please tell me if bitmain is legit or not, what would i have to deal with if i order from them. Thank you
