Crypto isn't helping there, that's just another form of regulatory arbitrage. If you're exchanging the crypto for USD or pesos anyway then what you're doing is still probably illegal.
I'm just paying independent contractors with crypto. How could that possibly be illegal? What the contractor does with the crypto is not under my control.
But if you could pay them in USD or pesos, you would? Can't you see how the government would take an issue with that, the very same issue that they have with USD or pesos?
It is not me as the remitter that is regulated. It is the contractor receiving the payment that is restricted on what they do with it in their foreign country. My understanding is that most of the countries involved have severe restrictions on hard/fiat currency transfers but not (yet) on crypto currencies.
