If you want to live in a place wherein BTC is heavily accepted, I think Japan is the best place for you, it may be expensive, but everyone in Japan, especially the government is friendly and not a threat to BTC, however, I cannot find a country that is low on expenses and tax and at the same time not a threat to BTC or a country that accepts BTC, if you do know some, tell me.
I have a different point of view. It is better to live in countries with the poor economy, low prices, and small salaries. In this case, you can buy more if you trade and invest.
Third world countries who also cater bitcoin uses, I guess budget wise this place can give you much suitable life as cost of living is much lower than
other well civilized countries, south east asia would be one of those countries that have tropical weather with lots of good places that you will enjoy
together with your bitcoin baggage you can live a good life.
