Maximizing profit, when the share price dropped from 5 to .5? I would say it is the opposite. They may have made more money selling, but now they are sunk, with some vague promises about next year. At least if they were hashing 1000 TH they would still be #1 for several months longer. Image means a lot in business. Then the share price may not have risen and crashed so traumatically. I think a lot of people are pissed right now because of how this was handled.
The share price has nothing to do with whether they maximized profit. AM got way overvalued because it was for a while the only ASIC company with a good reputation that you *could* invest in. The correction was inevitable.
I don't think FC would want to mine 1000TH on the Gen 1 tech, that would take about 7MW of power, which would generate a terrific amount of heat. There isn't a data centre in Shenzen that could handle that load.
AM have stumbled getting a second generation of chip out the door but their share price would have dropped anyway.
A lot of people are pissed right now because they bought in to the hype when the whales were quietly making their way to the exits. They deluded themselves.
