A company previously owned by the largest bank in Puerto Rico has successfully deployed an intra-bank / credit union fiat transfer app called ATH Móvil. (http://movil.ath.com/). Most people have it installed in the country.
The only needed information to send or receive fiat is the mobile phone number.
I wonder if it could be added so we can further promote Bisq inside Puerto Rico. Because of the financial crisis here, many people interested in bitcoin and the only option is Coinbase and Gemini at the moment.
