I think you are overselling Arnhem a bit though haha. Have only tried one of the participating restaurants of course, but they told me the BTC payment tablet is almost never used. And the other participating vendors are not really what most people (or atleast I myself) would need to live everyday life using BTC. I'm not trying to be a negative nancy here btw, just looking for actual useful real life places where its accepted.
