Effectively blocking entities from converting currencies in person is much harder than banning inter-country trade.

My dear home country made it illegal to trade foreign currency except at government exchanges, which trade only one way and at an exchange rate 50% worse than the real one. This just made illegal exchange shops pop up everywhere, and the biggest difference is that it's now dangerous and inconvenient to change money.

Crypto is one of the few ways I can wire money back to my family and friends.
