The problem is that everything is in the hands of one person.
First option : The mining gear should be confiscated from Garrett and shared through competent miners who could watch for the hardware, make it run and give updates. It is easier to run 1 or 2 unit than 20 units.
Second option : Sell all the hardware while it worth something, share the profit and end this mining group that is not mining anyway.
I'm for selling the hardware. I don't believe that Garrett can run multiple Cointerra at the same time and I don't think anyone want to help him.
