The future of Bitcoin may include a digital dollar at some point--maybe if the United States dollar is no longer the global reserve currency, or if the government wants to prolong the period of time in which its money is the lingua franca, so to speak, of the world, then it will establish some sort of crypto-facing currency that buys it more influence in a changing, multi-polar, Asia-centric world. Some sort of substantive action from the U.S. government will come at some point once various decision points pop up, which always does happen. I'm guessing the BTC future extends to governmental powers getting table stakes in the ongoing innovations in cryptocurrency; it'll be too costly not to.
