Hello Guys whats your advise on this, I have a friend who lived in the US hes made $150k, he needs advice if this amount is enough to set up a good living in Nigeria ,

whats ur advise guys?

tell your friend to do extensive research before he goes home. no business is garunteed to succede so he should also be ready to take some loses.
One thing that will always make money is real estate he could build flats and rent it out thats what my mother did.
