Pretty much. They can outlaw it, but they can't ban it.

And yes, a country's government making the ownership of bitcoin illegal would definitely be unfortunate, but let's be honest here: how successful are governments going to be in banning digital things? They can't even ban digital piracy and drug usage, what more with a freakin decentralized asset?

Again, bitcoin is decentralized, so how entities are going to bring it down. There could be coordinated attacks from governments, but i highly doubt that they will do it. What will be their point to bringing it down? There could be one compelling reason for them to collude with each other, ban mining, trading and everything about crypto. But so far countries are still divided with regards to crypto and bitcoin and we have more crypto friendly nation on our side.

If the governments of the whole world can come together to ban it, they will be successful, but the governments of the world can not have the same say over cryptocurrencies, which is the reason bitcoin can not be banned. As one country will ban cryptocurrencies, the other countries will not ban but support cryptocurrencies as an opportunity. Also as some countries ban cryptocurrencies, some will later decide to legacy it back. Cryptocurrencies are difficult to ban which makes bitcoin hard to ban, in fact, bitcoin in this sense can not be banned.

There isn't anything to be shut down. That's why you can't shut down Bitcoin. Because it's a network of computers running a certain protocol. Shutting down Bitcoin is as wrong as saying that someone can shut down emailing.

You shouldn't forget that if a government wants to shut it down, then another one may find the chance to protect it! It's beneficial to protect what others want shut down. Governments know the importance of Bitcoin and I'm pretty sure that they'll sooner or later play by the rules. They can illegalize its use temporally, but in the long term, they'll have to accept their “defeat” upon this. So no. I don't believe that every government will agree with each other for any purpose, not just for Bitcoin.

Actually there is, that would probably be the Internet consortium that has seven members that are spread around the world and they have the rings that is going to access a backdoor for Internet that they use to have a maintenance for the Internet to keep it running for 3 more months so yeah there is an entity that can shut down bitcoin.

Nobody can directly shutdown Bitcoin, but they sure can for sure shutdown internet for some time and that could greatly affect how Bitcoin network is working and it would create big changes in hashrate.
Before I was thinking this is impossible to happen but I see that some crazy people like Claus Schwab from World Economic Forum are preparing for this scenario and they are training and preparing for this.
They are calling this event cyber pandemic or cyber polygon and they claim it will have much bigger effect than corona pandemic.
Russian hackers could be blamed again, like we saw with Colonial Pipeline, and I even saw that Russian Prime Minister Mikhail Mishustin was part of this cyberpolygon show in 2020.
Purpose for this would be to have full control over internet (only place to  find some free information) and I think this can have big impact on Bitcoin and everything else.

I'm agree. Some countries can ban it but if you want you'll find a way to buy it. They can't just destroy the blockchain.

Maybe some countries can shut down bitcoin in their own way of law like disabling cryptocurrencies in their government. But to kill bitcoin it is imposible to do it, bitcoin now is like immortal and keeps changing peoples lives day by day with its overwhelming value. That is why many countries do not want cashless society and being ignorant about cryptocurrencies.

Quantum computing posed a threat on cryptocurrency way back in 2018 article that I've read if I'm not mistakes because it could control the Blockchain technology and the Private keys are at risks as well, but recent article that was published by forbes last December 2020 says that it will be no longer made that way, and to ensure Bitcoin and cryptocurrency safety, they will make a soft fork on Bitcoin  to ensure private keys from post quantum encryption.

shutting down the  internet will also affect  the entire financial system since everything today is dependent to the internet. thats not the option they see. regulating the miners seem to be the path they take. its the only way they can make sure because the physical aspect of mining gears/farms can be seized. if they can successfully do this. BTC might not be desirable to new investors.

still shutting down BTC will be impossible.
