The fall in bitcoin price as well as engineering issues have really taken its toll on Cointerra. I believe they could have actually done great if not for the over optimistic engineering mishap.
you may be right, although offering no compensation is the offense, as far as I'm concerned.
They could have delivered a 1Th/s unit and simply made the difference up in some way and kept people happy. I know I contacted them several times to attempt to bridge the gap and was simply ignored.
Flipping the bird at people is not the way to treat people that have dropped 6K+ on hardware. They get pissed, then they get lawyers.
All of this could have been avoided I think. I know I didn't set out to sue people and would have been happy had they simply thrown me a bone. This is always a last resort for me, and I think most people.
