Using Ethereum for International Transactions to Person(s) in Countries Lacking a Relationship with the United States

Hello, wondering if anyone on here has been exposed to using ETH (or really any crypto) and sending it overseas to family members, most notably those lacking a relationship with the U.S.?

I have friends that are from Central and South America, such as Nicaragua, Venezuela, Cuba, etc. that frequently send money back home but always requires an intermediary such as western union or even an individual that has found a way to do so. I am trying to make this more widespread amongst them if it is reasonable and the fees are worth it to them as opposed to going through whatever they currently go through now (a bank).

Process is below:
Open Wallet - convert dollars to ETH/BTC - send ETH/BTC to recipient - convert back into desired currency and back into bank account of individual(s)

This obviously is all done through their phone, and they don't have to stand in line in public exposing themselves to any government agencies, while simultaneously eliminating the banking aspect of controlling the transaction flowing to that country.

This should be able to work for any country that the west isn't involved with.
