Bitcoin is a wonderful coin, it's one of the best investment in the world right now, a lot of people has already started investment in it, some people has become rich through investing on Bitcoin and it has started to gain support from different countries while some countries has rejected Bitcoin for one reason or the other.
Any country that accept and support Bitcoin and makes it legal in there country then it is legal and is not a crime to invest in it, but if a country don't accept it or support and has made it illegal by there laws then is illegal and is a crime to invest in it.
Some countries is supporting Bitcoin and is even used for payment while some countries is fighting people investing on Bitcoin in that country, I really don't understand why a nation will be fighting Bitcoin why not accept and support it then make rules and regulations that those investing in it will follow, a lot of nations that has accepted Bitcoin are making a lot of money.
