Have you ever consider how far in the future is it to be able to buy groceries (bananas, onion, etc) using cryptos in the local farmer's market?
What are we talking about, a person in some city like NY or LA being able to buy from a small private shop that offers crypto payments or that becoming a possibility for the majority in this world?
The first scenario might (if it hasn't already) happen by tomorrow, the other...maybe in a decade.
In my case the answer is probably never as the local market in our town is useless, you find far better fruits and vegetables in hypermarkets and other chain stores.
