If you ask me, it's not the fact that he believes that it's fraud, or a scan, or a bubble. He's scared shitless when it comes to Bitcoin. The fact that almost everything he's learned over his lifetime is changing with bitcoin bending economic concepts, He doesn't have that power he used to have. The fact that he is firing and threatening a divorce means that it's gotten to his head. It's just not rational.
He isn't "scared shitless", far from it. He created fake, false FUD in order for the price to drop and when it crashed he bought millions worth under JP Morgan licensed businesses and made a huge profit from it.
I will admit it is quite strange that someone would trash the very thing they are investing in, but crypto markets are not your average ones.
That is a very common tactic, I do not know if you have ever bought an used car but that is the tactic many people use, after you get the price from the seller then you need to try to get a discount and the only way to do that is to pin point the defects of the car if you are good at this you are going to get a better price.
