I don't see groceries becoming available for crypto any time soon, and I don't see how people would buy your surplus for crypto if that's the only medium of exchange you're using. Is there a large untapped market of average joes looking to purchase whatever you're offering for crypto?

It'd be more viable for online goods and services perhaps, but you would be losing out on a lot of potential customers if you only accept crypto as payment and the artists that do accept crypto usually accept fiat as well...
