Even special cases like Venezuela where people are fleeing from hyperinflation, they mostly benefiting from the exposure to the USD. The only benefit is evading capital controls and price is irrelevant for that usecase.

Capital controls (blocking foreign exchange) are stupid because for every person selling a hyperinflationary currency, there is someone on the other side paying with a stable currency who is partially relieving some of the inflation pressure.

There are Venezuelans in Miami that send their paychecks back home to support the local economy yet capital controls prevent something like this from happening.
