I onboarded a lots of merchants during all these 10 years. Here is an example story
Now,. from 2018 ongoing I live literally using only BTC and pay for my groceries with BTC and get 10% discount all the time. I can order whatever the fuck I want from the local shop and they will bring it to my door, paying with BTC. Why? Because the shop owner realize that BTC is power and fiat is shit. He WANTS MY BTC !
