I think bitcoin will not change that. Bitcoins only have a strong influence on the world currency system. Bitcoins are growing around the world. There are many people who invest in bitcoin. But there are still some countries and big corporations that do not accept bitcoins. so bitcoin can not change the world.
It is us who can change the world, we are the nation's backbone and bitcoin is the result of human's creativity and innovation. It is truly a breakthrough, though it has not been recognized by other sectors but many claims its great impact to the world, and to Economy. It makes waves across the globe and many has benefited it. I just hope that time will come it will be adapted in other countries and realize its importance.
