TBH not sure how far $100k will go to pay developers to maintain and add features to a site like this, if that's his bankroll he needs to be making money pretty quick off the bat.
Good point. Even if he does make that million by 18, he should still go to college. 1 million at that age isn't a lot of money considering how long he has to live. Kid seems pretty damn smart though, so I'm sure he will figure it out.
I'd still head to college though, who knows the valuable connections he could make while there.
1,000,000$ well invested at 18 is huge but if he is using it to live, it isn't that much anymore
He will meet friends and learn things on life in college
He has invested it in his business. If his business survives for 5 years, chances are that it will allow him to live off of the business's earnings, if it fails within 5 years then he would not be too old to go to college then and finish school and still have most of his life ahead of him
