Read carefully. MBP has acquired technology from Cointerra, not chips. For the 100th shareholders' money. And it seems that they cheated.
Parameters Cointerra and MBP chips are identical.
Read carefully: I own MBP. I built 500TH mine. We have no technology from Cointerra whatsoever. 500TH was built with the 55nm BitFury chip and still runs with the same rigs to this day.
This is some kind of conspiracy theory of yours.
