Based on their decisions they might as well just get on with it and ban Bitcoin every week.
As for Tor, can they even actually use it? As using VPNs are illegal as far as I know.
Yes but VPN's still work in China. Even if it's banned people still use it. Therefore, I do believe that even if the authorities go ahead and ban bitcoins which is a major source of income for many people, I do think that they will continue to use it but ofc not on a large scale.
I think that ban is crazy and hard to enforce. If Elon Musk provides satellite internet, that's not a problem because nodes have a different way to operate. Another point is that the nodes in China are low compared to the rest so there is no concern about the decentralization of Bitcoin and ETH.
I do believe that the decentralization probelms is based not on this but actually on the laws that the government is making every second. How they are behaving with Bitcoins and other cryptocurrencies. Therefore the threat of centralization started from the day when they started asking for documents and banned VPN's.
China banning bitcoin is not important and I dare say nobody cares about what another country where they don't live in does to bitcoin or anything else. The FUD of China banning bitcoin is the problem and it will never go away even if not a single person in China used bitcoin! So in theory China can "ban bitcoin" every month as long as people are naive enough to believe the FUD.
Last time also when they banned bitcoins the price fell for a short time and everything recovered. I do think the legalization of Bitcoins in countries like El Salvador should very well balance out this.
