Not all countries are legalizing it or making any relevant laws. There are a very few countries who have legalized it and majority of the countries are not sure what to do with it. Either they don't bother or they are too serious about the negative impact of bitcoin. I am sure the majority of the governments are not taking bitcoin positively. Not all countries are progressive like Japan.

However, I believe legalizing bitcoin will help the mankind as a whole. A lot of new business will open up. A lot of new job opportunities will be created. More over, a lot of money will be infused in the economy which will increase the purchasing power of its citizens. It will have a very positive impact on any economy if a country legalize bitcoin. But they are facing a lot of pressure from the Banks and main stream financial institutions who wants to ban bitcoin. But the legal status is still unclear in majority countries.
