I guess the first idea is to raise bitcoin's marketcap by about a trillion dollars, a market size that can control much of the world economy. In order to move the world economy they need more than the world's oil and want it to be in the hands of the top countries alone. Silently, several U.S. companies are also participating in Bitcoin mining with the intention of holding for longer periods of time. Backing bitcoin is a good proposal, but the value of the assets will still sometimes be a great feature in the future before the detailed backing of the US dollar is made.
