I found a site selling cheap s9 r4 may be a fake.

[philipma1957]

Bitmanusa dot com seems like a fake.

Selling the r4 at 1099

Selling the s9 at 1300. The 13.5 th version.

As far as I know they are not real.



Bitmaintech.com in China real

Bitmainwarranty.com in Colorado USA real

The scammer is trying to pose as a middleman, only that he will take your money at checkpoint without delivering the goods
Nice try though
