I'm quite two-sided here. Imagine knowing Bitcoin is illegal in one place makes it more in demand or whatever, depending on the usage. Wouldn't that benefit the ecosystem? But I think there would be several consequences with that like shutting down of different mining farms or any other system that is related to Bitcoin.
I don't think the government will explicitly ban bitcoin or miners, but they will definitely make it highly taboo to touch it for banks. Especially if it threatens central banking powers. They will likely create a false flag scenario where bitcoin was used for drugs, terrorism, child pornography. They just have banks barred from doing business with crypto exchanges. It won't be a full press ban, but a stranglehold restriction which will probably be more effective than making it illegal (which I do agree would raise its value as a black market asset).
