There might not be doubts about whether they deliver, but there certainly are doubts about when they will deliver. Hashfast taped out early September, and is just now shipping, about 110 days later. Cointerra taped out early November, and isn't expected to ship until late January at the earliest, about 80 days later. February 24th is only 50 days away, and Black Arrow still hasn't taped out.
never thought of that, unless Black Arrow is just keeping mom.
