On a global level, El Salvador will be closely monitored by all other nations. The bigger economies will see this as an experiment in order to either adopt or shun bitcoin completely. It is both exciting and scary at the same time.
True, El Salvador has taken a big step, if I'm not wrong Japan also legalized bitcoin, but it's still a drop in the ocean. Countries like the US and European UNION would be decisive if they ever passed a law that would allow clear use of bitcoin anywhere in these countries, they currently allow bitcoin use, but they don't have bitcoin laws and many other countries follow what US and European Union do, if the US legalized bitcoin I think many countries in africa (including my country) would follow the same path. but unfortunately the presidents that the US has had in recent years are not in favor of bitcoin
