BTC has been in the news for a while now and has sometimes been clouded by FUD and controversy.
However, there is now an interesting map done up by Coin Dance that shows the legality of BTC around the world. While I am unable to determine if the study can stand up to scrutiny, it can be used as a general reference.
And for those who are trying to land their mouse pointer on the small dot that is Singapore, the map indicates that BTC is legal. 🙂
