could it possible? only governments accepted currency have physical notes fiat paper money. but bitcoin is globally online currency and only few countries accepted bitcoin. so physical currency or metal coin is not possible.
Thats right, just having governments acceptance so that physical notes or coin for bitcoin can appear in the market like the way of fiat. However, I also agree that we are not necessary to care about whether bitcoin may become physical notes or coin, because as we all know that bitcoin fundamentally characterizes its virtual or digital currency, we mostly exploit the benefits from its anonymous and the likes. Anyways, just let what bitcoin be - a digital currency with big usage.
