Great interview with Marco Montes, founder of Saldo.mx, about using Ripple to send money to Mexico. Interesting note: Saldo charges 7%, ~4% higher than typical bitcoin remittance options and 6% higher than it's biggest competitor, SendBitcoin.mx.
Marco Montes, founder of Saldo.mx, an app that lets anyone in the U.S. pay utility bills in Mexico Sending money across borders is expensive—but a new mobile app built on the Ripple protocol by Marco Montes eases the burden of U.S. immigrants looking to help their families back home in Mexico. Marco has been a regular at the Ripple Labs offices in downtown San Francisco as he built out Saldo.mx, an app that allows people in the U.S. to pay utility bills back in Mexico instantly and without the need of a Mexican bank account. It also drastically reduces the cost.
