There is no figure verified that many government officials are actually holding a vast reserve of Bitcoin under their stash. I am assuming that most Bitcoin in Russia are owned by private citizens and maybe even businesses. Russia is a fascinating country and if ever it can open its border to cryptocurrency business then this can be a big market but alas the government is entertaining wild ideas on Bitcoin and the whole of cryptocurrency, so they are coming up with measures to restrict crypto-related activities. They should have been running after scammers and hackers and allowed legal crypto business to flourish.
