NYM and the Most Unusual Payment Method in Crypto

I noticed a curious detail in the marketing of the crypto service NYM. Have you ever heard of it? If not, you have missed quite a lot - NYM is genuinely worth paying attention to.

It is a multi-layer network for private internet access. For simplicity, you can think of it as an alternative to Tor. At each layer of the network, nodes mix your internet traffic with the traffic of other users, protecting your metadata.

Users pay to access the network. Node operators, in turn, receive rewards and are economically motivated to mix packets properly and provide real privacy for users - otherwise no one would pay, and running nodes would become unprofitable. Proof-of-Mixing in NYM plays roughly the same role that Proof-of-Work plays in Bitcoin.

In Bitcoin, however, payment for the work performed by service providers (miners) is made exclusively in the network's native cryptocurrency - bitcoin itself. NYM services, as I learned today, can be paid for even... with cash sent by mail.

This makes me wonder who exactly this payment option is designed for. Is mailing cash really more convenient for someone than paying with cryptocurrency?
