What are the practical ways to spend crypto in Latin America?

I’m curious about the technology and infrastructure behind using crypto for everyday payments in Latin America.

What are the most practical ways people currently spend crypto in the region? I’m particularly interested in the technology involved — crypto payment processors, stablecoins, crypto cards, wallets, local payment rails, and on/off-ramps.

For those familiar with the Latin American market, which approaches seem to work best in practice, and what are the biggest technical barriers to wider adoption?

Things like transaction fees, liquidity, settlement speed, exchange-rate volatility, interoperability with local payment systems, and regulatory requirements seem especially interesting.

I’d be interested in hearing about real-world implementations or projects that are solving these problems, rather than investment advice or price speculation.
