13% tax for non-explained holdings is actually pretty attractive for launderers. Russia might become like Switzerland. Also the crypto-ruble is not meant to be an attack on Bitcoin but rather an attack on banks. There is an internal struggle between different groups inside the Kremlin. Putin is not the single power there, it's a myth. But the crypto-rouble looks like a good thing for Putin and the people, because the dubious russian banking system is weakened. It makes Russia less vulnerable against banking crises and foreign financial attacks, very clever.
