[MCU] Why is Klaue hunting for Vibranium in Black Panther when he was made a billionare by Ultron?

Because he's not doing it for money. He's doing it because he can.

Sneaking into the most advanced nation on the planet, stealing their most guarded materials, rubbing it in their faces and then leaving with them impotently stamping their feat and roaring behind him?

It's the thrill of getting one over Wakanda not just once, but over and over again, knowing that he's the best that draws him in. 

Sure he could just tell the world about Wakanda and watch as the new Oil Rush sets in and SHIELDRA sends in 100 B52 bombers with nukes to send them back to the stone age and get one over them that way... but he wants the personal satisfaction of victory.

It's even more personal after they branded him as well, every time he wakes up and looks in the mirror just resets his determination to show them just how much of a failure they are, how they can't catch him.
