I was just qurius to know most of the bitcoin users are russians
I don't think so. I think there is not enough basis for this claim. For sure there are many Russians who are part of the Bitcoin community as much as there are also many British, American, Japanese, German, Indonesian, Filipinos, Indian, Chinese, South Africans, and other nationalities involved in it. I believe that the circulating supply of Bitcoin is widely scattered across the world. Bitcoin is very much international, after all.
The same is true with altcoins.
