If you will ask me what my opinion is it will just need a few regulations to be implemented before it will gain its global acceptance by the different governments around the world. As of now government sees bitcoin very dangerouse and threat to the global financial system so they wont accept it until they put a regulations on it. I believe that it would be great if bitcoin is directed legitimately. It could happen. but I see that bitcoin is starting to be accepted by large companies in the world.
