Hi, Godspower, yes it's a profitable thing to venture into. You can make a lot of money in it, after all, that how Dangote got rich. He started out buying commodities in the Nigeria stock market and that is the same story with Tony Elumelu.
Now Dangote is in charge of all Dangote commodities and Tony Elumelu was able to take over Transcorp and UBA bank. Maybe one day, you too will have a big company and list your company on the Nigerian stock exchange.
This is why this website is great. it tells you what investments are the best to tap in to in Nigeria.
If you have any other questions, feel free to post it here and someone will answer it for you.
