Further, Wise offers their multi-currency account, including in El Salvador (https://wise.com/us/multi-currency-account/) and allows you to store any of 56 currencies without conversion and offers banking details in 9 jurisdictions. It's kind of perfect for remittances because you can have your US parties ACH to your US routing and account number, and it appears in the multi-currency account, free, and very fast. Or $7.50 to receive a wire, instantly.
[edit] I'm not knocking crypto here, I'm trying to understand what they've built and why. I don't know why they're using crypto here at all. I'm seriously confused about their technical payments architecture. They seem to only use LN to move money, and between two of their own custodial accounts at that.
For what it's worth I've listened to over an hour of podcasts with Jack Mallers.
