Russia is going to recognize bitcoin,so is it a potential and big market?How can I know more about Russia's market?
Well, I can tell you as a person, who lives not far from Russia and has a lot of friends there, that Russia is quite far from adopting bitcoins. Just considering that it is a big country with approximately population numbers 147 millions there are people that know about bitcoin and even started using it a couple of years ago. But MOSTLY Russians are not familiar with BTC. I guess it now depends on government. And if the government accepts bitcoins, for sure it will become popular, commonly used and, I think, will influence bitcoin price 
On the other hand if we just treat it as a hypothetical, assuming Russia did allow Bitcoin that would definitely create a huge market over there and probably drive up the price of Bitcoin as more people use it. Russians might even start using it exclusively.
