The government can ban bitcoin, exchanges, and miners, but they can't prohibit people using it under the radar, bitcoin is the money of freedom.
But the government can control the country and if they control their country from using bitcoin then it will have a huge effect from the price of bitcoin like the China do.
There has a lot of young millionaire from US that I heard from using bitcoin when they are kid because of their advanced technology so why they need to shut it down?
China is probably the largest market for bitcoin. China's ban on crypto has made people much more aware of bitcoin. And Chinese people trade bitcoin and other cryptocurrency P2P.
Which is also the real intention for cryptocurrency. Many of the merchants too accept crypto in China despite the ban.
US is a much more friendlier nation for freedom of people. And they'll probably not go against a lot of people to restrict the use of bitcoin in the US.
