Took me 1 year to convince my landlord to accept BTC for rent. Now I have even an agreement with him to pay all the rest of the utilities included in the rent, paid in BTC.

Also you should try to convince your local small groceries around you to accept BTC. I did that and now I have 2 that are fighting for my BTC, each one trying to bring me anything I want, only to pay them in BTC.

I literally live only using BTC from 2018. No more bank accounts and other bullshit.

Is not that hard to convince them, just take time and patience.
