Cant call it a scam. Dont get me wrong, there is no way in a million years I would buy one, and dont agree with Bitmain dumping used equipment but all the information is available.  Anybody looking to spend $12k should be bright enough to do some research. 10 seconds on google or on here and you have 1000 comments explaining why not to buy one (ROI, fork etc.).

As MindfulPar mentioned at the start of this thread, Bitmain even put on their site about the possible algorithm change. Anybody stupid enough to buy one after all the warning...its their own fault, not Bitmains! Bitmain are just greedy and dont care about the damage to crypto's.Teach them a lesson nobody buy one!
(Buy the way I bought a first batch A3...not regretting it but wouldnt mind Sia incresing in price a bit!)
