4Viktor Vekselberg – Net worth – $16.8 billion
Viktor Vekselberg, whose full name is Viktor Felixovich Vekselberg, is a Ukrainian-born Russian businessman, and the owner and president of Renova Group, a large Russian conglomerate.
With an estimated net worth of $16.8 billion, the 57-year-old billionaire opened last year a private museum to exhibit his Faberge collection, as well as several pieces of Russian art.
This year, in February, he announced he will offer a 3-room apartment in his Azimut Hotel in Sochi to Tatiana Volosozhar and Maxim Trankov, the pair who won the gold medal in the winter Olympic games. Nice gesture!
