Or I could just skip all of the convenience and regulatory stuff that will have to be built up around bitcoin to make them mainstream usable and just continue to use US Dollars which already have all that infrastructure in place. Using bitcoin for currency as a whole (IMO) is almost like a misguided application rewrite -- sure, at the beginning it has all these advantages of being light and nimble and having limitless possibility, but by the time you add all the stuff users actually want/need back into the system you wind up pretty much right back where you started with the old heavy app, perhaps with a shift of power behind the scenes (from the old architect to the new architect, if those are different parties), but nebulous real advantages for end users at the end with a lot of transitional pain in between.
