Bitcoin banned to use as a payment method for IPs, since that would have been a good way to dodge taxation. But that's not so different from the multitude of other laws pertaining to what IPs can and can not do with other digital currencies and payment systems.
I have not heard that in Russia banned the use of bitcoin with changed ip. But I heard that in Russia all companies which provide user access to the VPN service to report to the authorities the real ip of all users. I don't know how it will be done, but the Russian security services are experts in the surveillance of people. I don't understand why they always vote for dictators. Probably for this reason they live.
