I disagree. Sure, he doesn't understand bitcoin at all beyond how it can be used for illegal activities, but I think he genuinely doesn't care and thinks it's a joke. You are looking at a guy that has a fund that moves trillions of dollars a day while BTC is still a drop in the sea of money.
He is just looking at it from the perspective of a power drunk guy that can't see any treats to the status quo as realistic.
