Why not Germany? The only country in the world with no speed-limit on 70% of the Autobahn! Yes, it is heading downhill right now with his clown socialist climate hysteric government but this might change soon again as people seem to wake up. And Germany has a big, very active bitcoin community (e.g. einundzwanzig). No tax on BTC profits if you hodl at least 1 year should you ever plan to convert to Fiat.
