That's what you get for stealing from Putin. What you've failed to explain is why would Putin essentially steal from himself. He's more or less the Tzar, and he can take whatever he wants whenever he wants. I doubt he even remembers what money looks like.
I don't believe it. Is he rich? Without a doubt. Is he "richest in the world"? Not a chance. Three letter agencies from all over the world would be all over such juicy evidence given his lack of compliance with the wishes of their governments.
