Amazingly shortsighted. The primary beneficiaries of this will be organised crime, who will now be able to wash the Bitcoin via El Salvador to convert it to dollars, which they can use to buy trade items and export the profits. The number one export of El Salvador is actually people. If they were concerned about remittance fees they could just set up a bank in the US with low fees, instead of getting kickbacks from O…
The point about opening up a bank is interesting though. The amount of money WU is skimming off the top must be a non-negligible percentage of the country's GDP. There's gotta be a less pie-in-the-sky way to disrupt that without making El Salvador a money laundering haven, which will absolutely happen with this idea.
