No sane person uses Bitcoin as a currency because it is a fundamentally unsound ponzi scheme for suckers. I don't want my salary to be subject to the vagaries and manipulations of the Bitcoin exchange rate.
"Unsound ponzi scheme" could just as well be applied to any fiat currency. It has all the same rules (early entrants are more privileged in "the game" and can invest to out-perform younger players). It is very odd to hear people applying such qualitative judgments like this when the alternative is a currency that is actively debased by its issuers. Or do you think the inflation we've all suffered under isn't a problem?
