Why does he insist on Bitcoin? Their biggest use cases are 1. incoming USD payments from relatives in the States and 2. Retail USD transactions. BTC is really bad for both of these. Why not stablecoins on some cheaper chain?
The new economy needs a mix of both.
And regular folks are just trying to survive - they heavily depend on USD from relatives, but they pay massive fees to corrupt institutions. They are trying to work around that using BTC, but it also has high fees, and brutal volatility on top of that. If your monthly income is $500 and you risk losing 20-30% of that to fees & volatility, you're screwed. No wonder people protest in the streets.
What they really need right now it a stablecoin on cheap network. It's not gonna change the world, but it's gonna solve their biggest problems right now.
That, and we could link the El Salvador and U.S. bank transfer ACH networks to make sending and receiving money cheaper. Considering 2.5 million Salvadorans live in the U.S.
Mexico and Panama have already done that.
