If it gets pushed in a traditional way, it seems as if it will just be the same thing as fiat. No value and much greed and a lot of manipulation.
Bitcoin can't really be manipulated. Bitcoin derivatives, such as loans and options and such, can and will be, just like they are in every other currency, but there's really nothing anyone can do about it. Want to stay safe? Don't invest in anything risky. As for greed, that's not a bad thing, as long as it is satisfied through production and business instead of theft.
