What do you think will benefit it?
I think the acceptance of governments will be the decisive factor for the development of bitcoin. Because every time a country accepts bitcoin, the market will be expanded, and that's a good opportunity for bitcoin to grow.
Indeed government of each and every country is a representation of the public of that place so you are hundred percent right that a drastic change will be visualized if the government accept bit coin as legal crypto currency because the people of that country will feel free to invest more and more in bit coin without getting frightened or worried.
This will also favor bitcoin but the main thing is to arrange public seminars to draw attention of common people toward this profitable coin by this way there will be much more investor coming toward this coin and the advertisement through proper way will also give benefit to the bitcoin and on top of it if people will start using it government will have to bend the knee in front of mighty bitcoin and that will be epic.
