Yeah, billions and billions: https://youtu.be/u_aLESDql1U

The more I think about Trumpian strategies the more I suspect that he got some friends together (or they came to him) and decided they'll short everything, then he'll do this for a while. He and those friends would be able to 'generate billions' that way, by legal insider trading (since we learned that anything he does "in an official capacity" is legal and he can pardon anyone who ever got caught).

Last term he did some tax on bauxite that had a similar effect of costing billions to a whole industry that processes or buys aluminum, but one of the few bauxite mines in the US, run by a Trump ally of some kind, made bank.
