The government's role towards Bitcoin has been more negative than positive, and here we are, Bitcoin continues to survive. Thanks not to the government but the huge Bitcoin community, so let's not misrepresent facts.
Bitcoin is just a financial market, its rise and fall depends on the cash flow of the market and the United States is the country that controls the world financial market as well as the largest market in the world. Don't deny their role and influence.
No doubt that the top world countries' actions affect Bitcoin, especially the US, because Bitcoin is paired with the greenback (BTC/USD). But has that been the reason for Bitcoin to skyrocket over the years? Heck No! Like I said, thanks to the diehard community of Bitcoin that sustained it to this time, and also attracts more adoption.
Suppose the country that bans bitcoin is not China but the US, the world's largest financial market. What would happen and what bad things would happen next if the EU, its allies and much of the world followed the US lead?
In that case, Bitcoin will be devastatingly affected.
But you are getting the whole thing wrong, it's not about banning or not, it's about the survival and adoption of Bitcoin, and the appreciation of the price of the coin (all conditions being equal, like other assets). My point is that Bitcoin does not need a certain person to survive, it has always been like that. It rather needs its COMMUNITY, and it's this community that has helped it till now, and not a certain individual.
Even with their good or bad policies, Bitcoin will survive. Why? Because it has a huge and diehard COMMUNITY.
