What they might do at some point, is prohibit selling goods for bc, this is possible.
Mining / exchanging and buying outside of the country, or buying virtual goods will not go anywhere for sure :)
Again, another Orwellian-themed fake news about my place (or am I getting paranoid?)
UPD: just read the article at http://genproc.gov.ru/smi/news/genproc/news-86432/ -- yep, no new laws, nothing -- "measures will be taken to prevent fraud, etc."
The overall impression is, they are going (a some point, not now) to explicitly delegitimize cryptocurrencies as a means to make payments officialy, but not ban / outlaw using the mining tools, or exchanging the bitcoins.
