CBDC will be particularly hard to implement in the US. I could see it being an issue that causes official secession of some states. But definitely the establishment will pull a cyber attack and use it as pretext for something nefarious. That I am confident in. 

 Their Swift system is open to attacks, so I can't see them implementing cbdcs any more secure.  The digital Sand dollar is a cbdc which can still be exchanged for Bitcoin.  Personally, I'm not worried.
