The cat is already out of the box. There are so many cryptocurrencies now, some of them fully anonymous like Monero.
The russian government is sure trying get influence in Bitcoin. They're planning on building a huge mining plant to compete with Chinese miners. Mining is currently mostly done in China.
The Russian central bank has also been speaking about introducing a centrally led coin - the cryptorubble, but I'm sure many Russians are sceptical enough to not jump on that.
