It's not an obituary, it's a fact. I am tired of rehearsing how a currency is enforced to be accepted in the issuing country, has a monetary authority etc. Otherwise while theoretically it could be called a currency, that's a thing for dictionary writers, it's just not usable in everyday life therefore anyone pushing for it has a not-entirely-straight agenda. There's no killer app for bitcoin yet and it's hard to even imagine a (legal) one.

It's possible future blockchains will be better but so far, this is not.
