So it seems their 20TH will just suddenly be there at the end of next week, cause they've said that is 'a promise will not miss'. I really think they need to find another engineering team.
Seriously. I understand it takes a specific skill set to get these miners going, but at what point does it become more cost effective to just get someone else that can do the job to do it. Maybe they secretly have like 15Th going, and are just working on the last bit...but i doubt that's the case.
It is even worse if they are mining secretly with 15TH now. It means they are dishonest and stealing money from the investors. Therefore, unfortunately the case that they have failed to solve the stability problem again is already the best scenario. They've mentioned out-sourcing the assembly in previous updates. But now the problem is not that the assembly is slow, but even the one worked before stops working now.
