Someone asked me if you can do without bank accounts with bitcoin. I said yes and I told them you can even be happy!
I started to be interested in crypto from the beginning, but I considered them (and for a long time) as an interesting and sophisticated cryptography experiment, without any effect on real life.
You want for the continuous fluctuation of their value, you want for the impossibility to spend them easily in public services or to pay bills. A few years ago, even exchanging or selling any crypto for fiat money wasn't easy at all... far from it.
