Not really any new info there for anybody who has followed basic economic news but still I would take these sorts of predictions much more seriously if he offered some kind of proof that he's putting his money where his mouth is. If he thinks the dollar will collapse, he could post a proof that he's got some crypto wallet with his net worth in it or some S&P500 puts, whatever. Otherwise, it's just more empty Twitter chatter.
