Money's killer app is that it can be exchanged for goods and services and is a standardized unit of exchange. Bitcoin can do that too, albeit slower, less secure against the risks most users face, and less throughput, but the problem Bitcoin has is that anything it can do fiat can do better. Or, if that's not quite true, the things that separate Bitcoin from fiat are trivial or make Bitcoin worse.
Bitcoin is basically a kind of musical chairs for money. People buy in and try to get out and maybe they make money and maybe they lose money. People will play this game, clearly, but that doesn't mean Bitcoin is the future of money anymore than casino chips are the future of money.
