And that’s exactly what Bitcoin is. I don’t think someone with his mental faculties would have been naive enough to not realize how it could and would be used.
In fact, it would have an extremely strong chance of doing so due to it's better store-of-value qualities that would cause weaker currencies to flood the market and go to zero as people transferred their wealth into the harder money.
For example, Ilya Sutskever was apparently at the helm of the now-aborted coup. Look at any picture of him. The guy fancies himself a leader of a corporate coup but lacks the social awareness to shave the ugly scraggly remains of hair off the front of his balding head. Nothing wrong with being bald, but you can at least tidy up your hairline and not be intentionally ugly. Appearances matter, particularly in a public-facing leadership role. Even SBF was smart enough to turn his dishevelment into part of his marketing. Ilya lacks the personality to pull such a thing off, and strikes me as the kind of guy who just doesn't expect to be judged for his appearance, and if someone did he would probably make some moral statement about judging books by their cover. He would be technically correct and completely ineffective, just like his coup attempt.
