Why USDC works for hosting in Peru
USDC is fully reserved and regulated, which suits buyers who want a stablecoin with published attestations. In Peru the alternative is a card billed in dollars against a Peruvian sol (PEN) balance. A local card is normally billed in PEN, and whether a dollar invoice adds a conversion fee depends on the bank that issued it.
Paying from a wallet takes the bank out of the transaction. The invoice is priced in US dollars, the USDC amount is locked for 15 minutes at the live rate, and the transfer goes straight to the address on the invoice. Nothing to approve, no merchant category to argue about.
