That's look intresting but im sure that we will not need btc as reserve US currency. They will want to control it
The U.S are not going to make BTC a part of their reserves, there is no reason why they should do that, the U.S dollar is stable, and the U.S economy is a healthy one, so they have no business with a BTC as part of their reserve. BTC is decentralized, so direct control is not possible, they can only control through regulations, which they are already doing.
