Bitcoin is pretty much settled as a commodity now. I think a paradigm shift is going to be needed for it to become a daily currency. You have to also keep in mind that the current infrastructure behind bitcoin does not allow it to become a daily currency, due to scalability issues.
the prime purpose of bitcoin originally was to become the world's currency, but it seems it did not happen. however, today bitcoin has a better use I think, that is as an investment. although it has failed with its original purpose.
