Quoted slightly out of context so let me put my full thoughts here.
I said that bitcoin is an idea that has gained traction because enough people have accepted it, assigned it value, and allowed it to become a medium of exchange. I also said that it has gained traction as a result of the fallout from the financial crisis and a certain subset of society becoming disillusioned with governments and their handling of the crisis.

I am not sure if it will ever reach that level, though.
