ok, well from my point of view both hashfast and cointerra are horrible failures....
Thank you for being logically consistent and fair.
I disagree with your conclusion, but appreciate your even-handed approach.
The attitude of 'HashFast can do no right despite their chip working great, and Cointerra can do no wrong despite having no chip' got old, so I'm putting a stop to it.
Always bet on Gödel...
