The United States have strict regulations on these cryptocurrencies, but not outright banning them like what the Chinese government did. However, assuming that it’s gonna happen, it will cause a huge impact in the entire crypto market. We could see a decline not just on the price alone, but for the number of wallet holders as well like what is happening in the UK now.
They are making money with bitcoin so there's no reason to ban it, All they can do is regulate and put some restrictions on its usage on its country. But so far, i dont see them going after bitcoin like china did anytime soon.
The USA has a different kind of government compared to China, and we never heard the news or even rumors that the USA is planning to ban cryptocurrency. In fact, the news is more on regulation, and that the fact that they are talking more about regulation, means crypto is accepted already.
