Fiat, while in a way better shape on that part, is not perfect either. I don't know for other countries, but here in france we have three means of payment : payment cards, paychecks and cash. Cash is annoying to manage because of its fixed values, always having to deal with rest and counting. Paychecks, you never know if a merchant will accept them (it's more and more rare). payment cards have weekly rate limits, and we have no mean to know before paying for something how close you are from it, except if you track every single payment you make. Last year, I tried a bitcoin payment card. It was not practical because of bitcoin volatility, but there was something super cool about it : it was a prepaid rechargeable card that I could recharge in the hour, by sending bitcoins to it. I always knew how much I could use on the card and could basically use everything that was on it, without fearing to hit some obscure limit. This was the perfect payment method for me. I hope we'll have something similar to this but with non volatile currency soon (I know this exists for fiat, but I have to wait like 2 days for a wire transfer to happen, this is not practical).
