bitcoin isn't a viable alternative to money as it already is a form of money.

bitcoin isn't a viable alternative to state issued legal tender /fiat as it subverts some of the intrinsic qualities that states love about controlling their currency(I.E... the ability to steal from you without actually knowing you or visiting you through inflation and the ability to track and control your behaviors and punish you when you misbehave.)

Don't expect Bitcoin to replace Fiat anytime soon, expect states to remain ambiguously or aggressively antagonistic to it as they hate competition.
