GME was easy. Hold the stock, sell it to the shorts. How do you do that with US dollars?
Secondly, as crazy as this sounds, would it be one reason for the Fed to preemptively drive inflation? (I suppose a low constant multiple in devaluation wouldn't blunt a short squeeze peak entirely, but might make it less sharp?)
If you believe OP, borrow as much foreign currency as you can and exchange it for USD. Back in 2007-2008, many Canadians emptied out their savings to buy USD at incredibly favorable exchange rates. Within a year or two they made over 30% as the CAD fell and the USD recovered.
In your comment it seems that you are suggesting there was some kind of squeeze from retail holders that caused the price rise in CAD to USD... I find that tough to believe but have not considered it.
