There is no way the country will be able to close bitcoin. Even though some governments prohibit bitcoin circulation in their country, there are still people who hold and use bitcoin. Every country has a very enthusiastic crypto community so that the country is unable to stop the circulation of bitcoin.
It's obvious that no one can shutdown BTC, or stop people from owning BTC. No matter the laws placed to prohibit it, people must still own and make use of it. Imagine some countries are prohibited from using certain exchanges, yet they access it via VPN. This is just an instance to show how much interest people have built over the years for crypto, especially the king (BTC). Most governments however are trying to protect their citizens from the cons of holding BTC, without necessarily looking at the pros. Some governments think BTC is a threat to their own local currency, reason why they try so hard to prohibit it.
