9. Taha Mikati
Taha belongs to Lebanon and has established a communication related company along with his brother. They are one of the largest telecom group since they are providing their services to all Middle East as well as Europe and Africa. This clearly shows that telecommunication is another mint making business which attracts money like crazy.
His brother is currently the president of Lebanon, therefore, he enjoys complete freedom and authority. Recently they sold some of their telecommunication rights to other companies, however, they did so at amazingly high rates. His current assets are about $3.4 billion which are expected to grow once he expands his business.
