That's the goal, but getting on zero fiat is nearly impossible in the USA. How do they eat and pay for gas?
Luckily for me, my partner still has access to services as we need them. She does have a cash app account and debit card that takes care of the dirty fiat deals. But they have lightning and deal only in Bitcoin. Cash app is awesome. I don't work a regular job. Mining and hanging out here is how I secure my future.
