Apparently, Hillary and her "friends" are getting worried about Bitcoin's disruptive potential.
Be aware that those who are powerless to do something tend to rant
(it's not for nothing that real power is called gray cardinals).
Also, do not forget that in order to stay in the saddle, politicians of such a level as Hillary must periodically stir up the interest of their voters, so they have to create a news noise based on the modern interests of the audience. As a rule, if she understood something in this, then she would have been more worried about the Middle Kingdom and viewed bitcoin as the only adequate lever of pressure on China. I am not saying that Bitcoin can be a political instrument, but with the support of the US government, Bitcoin can be a breath of fresh air for the entire American economy.
