The fastest evolving industry is currently the Application Industry which is assumed to reach$ Billion in, thus developing an App as a home-based online business could be a wise decision. However this requires a lot of creativity and feasibility studies in order to avoid risks as much as possible, taking into consideration that Egypt is a third world country and not much technologically developed.

If your English is good, you can start by giving online courses about your passion on websites like UDEMY, the course can be about anything you're good at and I literally mean this. Also You can write books of - pages on Kindle amazon.
