You are the bitcoin.
If they can't stop you running bitcoin node at home, they can't stop the bitcoin.

If it is possible to wipe bitcoin out from existence, they could have do it since, as bitcoin is against the desired of monetary policy makers and the world elite. The only way they can attack it is through media propaganda outside that nothing can be done to wipe it out from existence.
