Unlike the internet, I guess they found it pretty impossible to control anyone in the country from being able to use it - so they might as well legalize it, tax it and have businesses making profit from it. Sounds like it will still be somewhat restricted and they what to contain it to certain areas of the country, at least from the mining perspective. It's a bit surprising that the ministry of finance and the central bank were so at odd's with each others opinion, maybe there is some kind of rivalry going on between the leadership of these two institutions and this is an outlet. The central bank, which controls the normal money flow, has lost it's case to the ministry of finance who is trying to innovate.
This was the case for years now and some nations for some reason still goes against it. Bitcoin is not something they could censor, China is doing and trying the same thing as well, this is not internet access where you could block some websites form the ISP, you just need to accept the fact that with the p2p trading options you could never truly stop bitcoin.
Definitely you could limit it, there will be some people who will stop using it because p2p would be too much of a hassle for them but the reality is that you can't really make money from this at all, you just need to accept the fact that it is a profitable thing for a nation that could make money if they do not ban it. Russia realized it finally and they are just going to make sure that they could get it legalized and taxed instead of banned.
