If Bob, who occupies one region of the crypto economy, wants to remit $200 to Alice in another region of the crypto economy, USD coin or tether are the most convenient options. Interposing a non-blockchain intermediary like Western Union into the mix would be a step backwards. That would introduce an expensive double-hop, much like a stablecoin remittance in the real world introduces a double-hop.
Should Western Union Worry About Stablecoins?
