yes, they can stop bitcoin through the regulations they make. you can see several countries that have made regulations limiting the use of bitcoin in their country, such as bangladesh, where their citizens cannot use bitcoin freely because the government has banned bitcoin. from this a government can limit the use of bitcoin whenever they want and citizens cannot fight this because it is the jurisdiction of the government to be able to secure their economy on the grounds that bitcoin could disrupt the circulation of their currency.
when you check the history of Bitcoin you can see that government don't have anything to do with bitcoin blockage because they don't know exactly the technology of bitcoin because if they have known the technology of bitcoin by now they would have abolish the existence of bitcoin, on my own I know very well that bitcoin have what it takes to remain on earth and only thing government can do government can do to bitcoin is to regulate its power rate in that particular country.
You are on point and it's only God that can stop the Bitcoin, no matter how the government try, they can't stop Bitcoin, they can only limit or stop us from using it, which can't be possible, their plans is just to be in control or charge over Bitcoin, and since they can't control it, they are angry and wants to make it stop, they just keep trying and trying but can't control it and who knows what will happen if they are in charge or be in control of Bitcoin, by now, we could be paying to join or involved ourselves in crypto, by now, they would be using it as they want either for their selfishness or stop it from existing and I thank God is not done that way, it's decentralized assets which always makes me happy.
