if I have to be honest, I do not think that the bitcoin will ever do this anytime soon but I also think that it will never happen, its just too much to ask from the bitcoin.
The most are thinking this and I agree about this because I think its not possible, the dollar is way more used and another fact is that the bitcoin is also depending on the dollar market right now, when this will not be the fact anymore it got a small chance.
Bitcoins ain't depending on dollar market but the thing is, the valuation of bitcoins needs to be done in fiat unless we valuate it through other ways and that's hard in case people start using bitcoins that way because they are here mostly for profits...
