Leaving aside the arguments about characterization of the US dollar (or Swiss franc, British pound, Japanese yen, or most other more or less sound currencies on this planet which are "backed by nothing"), are you then saying that there are no advantages to using bitcoin, compared to US dollar? What's the point of using it, then?
Nope, not at all. Rather I believe there are tremendous advantages to using Bitcoin. After all, are we not headed towards a cashless global economy where everything is based upon electronic transfers of “credits” instead of dollars, pounds, euros, etc.?
You can pay or tip anyone online instantly, whether or not they know anything about bitcoin and support an economy of micropayments for microservices.
