It's good to utilize various currencies for various reasons.
I want some goldbacks just as a hedge for Bitcoin/crypto, and Fiat.
Plus it's just easier to tip people in physical sound money than give them a whole thing about Bitcoin, and how it works.
It says I appreciate your service, and I don't want you deflated, or bored to death.
If they catch on, they'll keep it, if not then I'll just take them back.
