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.

If you are in the US, what is your opinion on the common prison trope that smokes are money in prisons?
