For the foreseeable future, I am sure that more and more countries will legalize the use of bitcoin in their countries. Want it or not they have to accept it because of the development of technology that must include bitcoin in it.
It will eventually when they realize that some countries are making best use of the bitcoin and technology and it is helping their economy as well. This will put pressure on other countries as even they want to grow and make their people more employable and this is a the good field where more jobs can be created.
Yeah it is very necessary for the promotion of bitcoin. If we want bitcoin to be used throughout the world we should legalize and regularize bitcoin as much as possible. The use of bitcoin will increase when more and more countries will accept bitcoin as their legal and regular currency. It will take long time but finally it will take of the market worldwide. Till that time we should be patient and cool.
