to me the government of Russia has also not given yet any statement about bitcoin, therefore people are using it as legal currency, but if their government consider it as illegal then it will really become difficult for them to use it.
I think the Government of Russia will ban bitcoin although there has been no official statement. all countries know that the use of the bitcoin will officially make a country's currency can be abandoned. In addition to this is the issue of taxes, with the State would certainly difficult bitcoin collect taxes, because the Government had no control over bitcoin.
