Singapore is one of the most Bitcoin-friendly countries. Switzerland is another one. The government tolerates the use of Bitcoins. On the other hand, a guy was detained in France after a policeman heard him uttering the word "Bitcoin".
most of the european countries like sweden, denmark, netherlands are bitCoin friendly.
While most of the Asian and African countries does not. There are too many third world countries and they are still under developed. They are too obsolete to accept new technologies and gadgets. The government believe that Bitcoin can destroy the whole politic system so they decide to ban it without any reasons.
