Of course it is, that is what socialism is all about: The State is supreme. Bitcoin circumvents the State, so this is the natural reaction. The central bank is the natural enemy of Bitcoin, because Bitcoin makes banks and central banks obsolete. However it is a technology, so its like banning electricity because it may end the job of the gas lamp industry.
In this case it is very clear: Bitcoin removes the State and Banks power over money. Let it be, the wealth they reject will flow elsewhere, in the end they cannot stop it, no matter what.
I am even amused by this situation with the complete prohibition of transactions in cryptocurrency in China. Finally, the Chinese government has come to such a predictable decision. Now it remains to observe how such a prohibition will be implemented and whether the state will be able to control it. This will be a valuable experience for both people and states. We have seen so far that such attempts have not yet been crowned with success and, most likely, the state will not succeed this time either.
