No, the Fed won't allow any entity other than central banks to interact with their coin. The central banks will have to decide which digital currencies will be allowed and then they will have to sell them to the people. You know, the same people they told 2 years ago that they wouldn't need a digital currency. Then they will run into the technical issues bitcoin went through in it's early years. I wish them the best of luck, it will be a never ending hackathon.
