You COULD do everything from inside a Whonix "workstation" VM. No matter how badly you screw up, the most you can leave is a Tor exit IP and a (generic) Whonix browser fingerprint.
(This assumes basic non-tech OPSEC, of course, but you got that)
(And assumes that there are no secret flaws in commonly used encryption, or if there are, that the exploits target Putin over you.)
It will be slow, if you have good internet. No real change, if you have bad.
