Don't think that they're nuts.

Institutions generally have fairly accurate reasons as to why they would predict something to happen. They don't just put out random DDs like the WSB crowd.

Even though this might seem like a far fetched idea, it really is not given the fact that fiat is an ever depreciating asset that will eventually go to zero. BTC, if it indeed becomes the store of value in the world, would definitely reach these sort of valuations as a matter of time.
