Europe, Japan, Canada, Isreal, Korea, US, Singapore are some major countries where bitcoin has legal status. There are many other countries like India, Rusia those are preparing a draft for bitcoin legalization.
In addition my country Nigeria is bitcoin friendly, though recently government advised against bitcoin after considering the rate of cyber crime in the country but so far no regulation or banning against it. There has been live broadcast, newspaper advert and radio jingles on crypto currency in my country with fear.
