I agree that fiat will bust eventually, BUT I worry crypto will have very little effect if that happens. Without mass adoption you'll still be looking at an inability to spend it. I doubt people will adapt during a major bust because fiat will have already scared them away from currency in general. Bitcoin adopters will be able to trade among themselves, but I honestly doubt it has enough adoption in the near future to prop up the system in the event of a collapse. Upside is we'll be really rich post-recovery.
