I don't really understand the incident, which certainly the countries or governments in each country have different regulations, as china banned the bitcoin exchanges while in japan now bitcoin 100% legal, if they are placed in the same place will lead to disputes, I think there will be many problems if we only use one currency only.What if all nation use only a one currency or one global currency?, What will happen to our world?, What is the effect of every nation's or every country economy?, It can make people's unite each other?Any opinion.
