Leszek posted on this forum about plans to use 28nm technology in the 500th. Therefore, many 500th shareholders bought Cointerra's shares, including myself, with a view to the future development of 500th. Sorry but acquired technology was used in their projects MBP and those who bought shares Cointerra scammed.
I see. Maybe he planned to do something with them until their 1st gen chip came out poorly. But Leszek has never promoted that he would grow the 100TH/500TH mine beyond its current hashpower. 100TH was the original target. Leszek increased it to 500TH at no cost to the investors.
I'm quite certain nothing was acquired from Cointerra except an equity shareholder position. I'm the one managing the 500TH mine and can assure you there's not a single Cointerra machine in my facilities.
