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.
For me the best place to live with bitcoin is japan. Because aside from higher cost, it should be advance in terms of technology and we all know that bitcoin is the innovation of technology.
