For me it's no, because if the bitcoin change the Dollar, I think bitcoin value were going down because bitcoin is the basis of Bitcoin price in the market. Moreover, billion years bitcoin beat the Dollar in the market because trust of all people were already earn by Dollar.
What if the Bitcoin was officially pegged to the Dollar in some way? I mean by the Federal Reserve. Or, if the Federal Reserve made its own e-coin (BitDollar/eDollar) on a blockchain with its own rules, including pegging to the physical Dollar?
