Bitcoin still has frictions. I wanted to tip a waiter in bitcoin, he happily accepted, but I had to make him download an app. Even the simplest custodial wallet has to be downloaded, it takes time. Busy night at the bar. The boss comes and signals to him that he is wasting time. The app is there but he has to enter the phone no. for verification. A little upset (with the boss) he just leaves the phone there. He is now drying the dishes. I think I don't want to be pushy so I let him do his work thinking that I've lost the moment now. and later I go to pay, he's cleaning the counter and tells me if we can do next time. I'm sorry. 10€ cash would have been much easier. 💔
