I don't get this. Ok, I see that AM has to move into another market due to the competition of the other ASIC-producers. But USB hubs and immersion cooling? These are "regular" hardware, that means, you already have all the competition waiting for you! Even worse, the profit margins are already reduced the bare minimum and you are basically competing for efficiency in production. I don't see this as a viable future for AM as a company.
Don't get me wrong, I think that getting out of the ASIC market is a very good idea, especially if you didn't score the knowhow/production capabilities as Cointerra has. Simply said, the time of doing 65nm ASICs on deprecated Chinese production lines is coming to an end.
Hence, I think the only option for AM is to stick to Bitcoin-centered projects that do not suffer from the drawbacks outlined above. This will be most likely infrastructure providing services, for example hosting or some software-based service as a market. Maybe even consultancy, who knows?
