Depends on your definition of "legitimate", but Iran uses cryptocurrency to tax oil tankers going through the Strait of Hormuz. There is certainly some practical impact. https://finance.yahoo.com/markets/crypto/articles/iran-turns...
Interesting use case. Not formally legitimate but even the US would prefer it not be stopped as even small exports exert a large impact on the price of oil.
But a good example of a macro impact on the global economy.
