Mike Adenuga is now the second richest man in Africa after Dangote

There are 24 African billionaires this year, down from 28 in 2015. And according to Forbes, Nigerian businessman Mike Adenuga is the biggest gainer among the African billionaires. He is now worth $10 billion, up from $4 billion a year ago.
The significant jump in Adenuga’s fortune according to Forbes is attributable to new information on the value of his telecom, oil and real estate holdings. Angolan investor Isabel dos Santos and oil tycoon Folorunsho Alakija of Nigeria still remain the only two female billionaires on the continent.
