The "anywhere in the world" part is really huge. As of now, most cryptocurrencies aren't run by nation states, unlike traditional currencies. Cryptocurrencies have to potential to become a global currency that's fair to all.

I actually think that the nation states really missed out when they didn't mint their own cryptocurrency that has the same value as their physical money. If they controlled a currency completely, they could tax every transaction! Surprised they didn't jump on this.
