That's just shifting the problem one inconvenience further. How do you purchase cryptocurrencies without Visa/MasterCard/PayPal?

I'm not sure what options they have, but ideally, for convenience some kind of local country bank transfer, which could be to a local crypto dealer. That might take days but you might "stock up" on crypto to compensate.

Or peer to peer cash/crypto swap might be required.

Or businesses themselves sell some of their services with crypto.
