He will continue to criticize Bitcoin because that is his job. He just doesn't want Bitcoin to become an asset that is more popular than gold which he continues to defend. Even if Bitcoin is much more valuable, though he has been criticizing it for a long time, he will still stick to his position that it will end sooner or later, and everyone involved in it will lose their money. What a poor guy. He looks like a little kid whining, while everyone else just walks away and lets it be.
