It's very very close to impossible without exchanging bitcoin for fiat every once in a while. Otherwise you can pretty much give up on ever recieving any utilities.

I didn't say don't exchange to pay bills. I do that. But I KEEP all my value in Sats.
When I can pay in Sats, I do. When I have to convert, I do. I hate having to participate in a system I abhor. I try my damnest to extricate myself further every day.
I earn, spend, and save, in Sats.
Then it's actually incredibly easy. There's no challenge to it at all.
