Tyga
Almost to the half of the list is young Tyga, Michael Ray Nguyen-Stevenson, by his real name, a rapper from California, who started in 2008 with an independent album.
By the time he was promoting his second studio album he already released several mixtapes and signed famous Young Money Entertainment, Cash Money Records and Universal Republic Records who have under their care mega star Lil Wayne.
Two more albums later, many singles, collaborations with the biggest and baddest stars in the rap industry, Tyga managed to make a net worth around $10 million.
But with this kind of money the little baller was accused of never returning some expensive jewels to a Beverly Hills jeweler, who sued him for double the amount of money the items were evaluated at.
