Mind you converting $10,000 to naira which is your country currency At the rate of #500 per dollar, then the money will be #5,000,000.
Well I'm not judging what your plans are but just showing you the worth in your currency then you can go through your plans again and know what you will really do with the money.
Although I love the part of investment you mentioned which is very very important among all.
And you know the kinda situation in Nigeria now, even that money you mentioned still don't have value..
The economy is messed up
