The majority of all replies was stated that the government can't shut down Bitcoin and that is the fact.
Indeed mate, because if they can shut down bitcoin, they could have shut it down when it was widely used in the dark market for drugs trading.
There's no people or admin behind on bitcoin because that is created with open source code and anyone can access an improve if you are a dev. But the government has the power to manipulate and control people who are using Bitcoin but when you say totally shut down, no, that is not. Only few countries forbade Bitcoin but the rest are friendly on this digital currency and embracing the blockchain that the technology behind the bitcoin.
Big country such as China ban crypto but there are still some countries who are using it, maybe the government of China can shut down BTC in their area but bitcoin is not only limited in China, therefore they cannot stop it and bitcoin will continue to leave.
So, for investors, we should look at that reality, and be smart to invest in this early stage.
