Bitcoin is circulating in America as it is one of the largest bitcoin markets for investors and miners.
You are right, US has the largest market and miners, but also has the largest bitcoin ATMs, far greater than the second. We do not have to depend on the government before bitcoin adoption would continue, but just that the government should not do something that can discourage the continuous bitcoin adoption.
Also we should know that bitcoin is not only about US, it is about the world, even if US is discouraging bitcoin, what will happen is what happened when China discouraged it, governments on the world in all countries are not thinking the same, some countries will only see it as an advantage.
The US government especially Joe Biden sees bitcoin as a threat to the US dollar,and for this reason he doesn't want to promote bitcoin in his government but he has failed because bit coin don't need any promotion by government.
I do not think he failed, because he did not promote bitcoin. If he remain mute and do not talk about bitcoin, US remain bitcoin friendly nation. President is not the regulators, but I know how the president of a nation can be very powerful though and how his power and legislative power can override.
