Now, perhaps what you're suggesting is "I've got millions of units of money that I've acquired through locally illegal means and I want to transport that money someplace else and I don't feel like renting a private airplane and diamonds up my prison wallet are uncomfortable and I don't want to pay taxes or otherwise explain why I have a brand new S class I paid cash for." then yes, I'll accept that there is some grey area where crypto has a place (to explicitly work around legal regimes I dislike, would like to degrade further, and don't feel like dealing with).
Try this: you are a paralegal working with translating/notarizing documents from Spanish to English in Argentina. You have clients in the UK - a wine importer. You send an invoice for your work, it's circa GBP 2000, about 4 million Argentinian Pesos.
Then, you tell them about the payment options:
- pay via SWIFT. will have a 30% surcharge to account for difference between the "official" exchange rate and the "black" one, and the fact that it takes at least 7 days to clear.
- pay via cryptocurrency, which can be settled immediately, you can convert to Pesos faster and at a better rate than the official one.
Are you saying that the only correct moral action is to go through the banks?
