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.
No he's not scared to bitcoin. It's just a propaganda a we know as banker is making money out of thin air and with their loan products they are using their mouth for it to attract their borrowers to borrow some more. And just like in bitcoin, he wants to buy at dip and he uses his mouth just to scare people to sell their bitcoins by indicating that bitcoin is a fraud, a scam, a dark market money and so on. He uses his popularity when it comes to money making, now he got a lot of bitcoins now bought at dip, we may know he'll eat his words and put a statement that bitcoin is not fraud or he'll make a public apology.
