I had a history professor in college say the the world operates in a series of divergence and convergence. For example, the internet brought ideas together in one place, then as complexity grew, the internet diverged into a series of places to get different thoughts. The same are currency came together to form the dollar instead of trading, with the internet, there will come a currency for every-single thing. It provides for more accurate value in the long term/across the whole strata. Where as a dollar goes further in some places than others, a token should be worth the same in Indonesia as it is in Russia.
