Prove that he is a billionaire. He is not.
Figures released during the legislative election of 2007 put Putin’s wealth at approximately 3.7 million rubles ($150,000) in bank accounts, a private 77.4-square-meter (833 sq ft) apartment in Saint Petersburg, 260 shares of Bank Saint Petersburg (with a December 2007 market price $5.36 per share[353]) and two 1960s-era Volga M21 cars that he inherited from his father and does not register for on-road use.
It’s well known that Putin has billion hidden in Switzerland and Lichtenstein. He looted his country just like the oligarchs under Yeltsin who personally picked Putin to be his chosen successor.
