aris is technically correct. They are not legally allowed to bring a ton of USD into the country (if they're even well enough off to do so). And legally, they have to do so at government-mandated exchange rates (which no one does, because everyone buys/sells on the black market). Surely people are using USD where possible. But likely, they're HODLing their USDs (against the rapidly inflating Bolivares) wherever possible, too.

Meanwhile, no doubt some are using crypto to supplement their incomes/savings as well.
