You can get wealthy in different ways; you can marry into wealth, inherit it, work hard for it, build it up from the ground up, win the lottery, etc. It takes a while to gain entrance to the billionaires club if you are building it from the ground up, and so it is obvious that most of the people that made this list of top 10 youngest billionaires in the world inherited their wealth
10. Julio Mario Santo Domingo
Like most of the people on this list, Julio inherited his wealth. He was an American DJ before inheriting a fortune from his late grandfather, which was 15% stake in one of India's biggest beer companies, SABMiller. The 30 year old has a net worth of $2.5 billion.
