Russia banning BTC is old news. It has very little effect on btc.
Last year when China banned Bitcoin we had an all time high price. Fueled by Chinese buying bitcoins.
The Chinese started to attempt to more strictly enforce the ban on bitcoin shortly before we saw a pretty severe price decline (that was likely caused by Chinese selling).
I don't think the russian market for bitcoin was really ever very big so I don't think this will be a very big deal however it is certainly not something that can simply be ignored
