The moment all the countries convert to crytocurrency would be the beginning of many amazing things to happen to the world and the financial sector, the process sending and receiving funds worldwide would become very fast and easy, it would lead to growth of businesses and make life easier for citizens of the world.
I also believe with this. The economy will rise. There will be no poor anymore, the poor will be looks like rich people of today. Everyone have work and there will be no child in the sidewalk starving. Bitcoin will bring us a better life if everyone accepted it. Therefore lets hope for it to happen.
