Mikeywith, what really disturbed me is the part the guy says, "Because new miners rarely have such problems in China, it is likely that they have been injured during transportation"

So how do they transport the miners within Mainland China? By teletransportation as in Star Trek? Scotty beam up the miners to Shinchong farm? Nahhh they ship them the same way the do to other parts of the world.

So thinking about the way that people operates, cheating and lying all the time, I have come into a conclusion that Bitmain have two assembly lines, one for their own farms and customers within China, the other for the rest of the world which is low quality and compensates the extra costs invested into the "domestic production assembly line".

Moreover, they don't want more competition so they take your hard earned money, send you a crappy machine and in 3 months max you are out of the business either because you ran out of money or you are not willing to spend more in some other brand of equipment and in the top of that you have no working miners either.
