Get a Coinbase card and load it with 5 USDC. Go to your diner and buy your coffee with no conversion fee. What's the difference between this and the diner actually accepting crypto?

I don't know what any of that is. I always pay cash. When I say bitcoin, I mean literal coins.

usdc is a digital token backed by usd available on many blockchains.

you can buy a few usdc tokens and pay for coffee using them seamlessly.

My coffee shop doesn't accept coins at all be it usdc or whatever. When I wave over a POS terminal, are these USDC converted to USD on the spot like a bank transaction?

yes

> ²Coinbase will automatically convert all cryptocurrency to US Dollars for use in purchases and ATM withdrawals
