I'll give my two cents and say this:
don't get blinded by other people making millions with illegal shit. You can make the same and actually sustain it long term by doing legal stuff. If you want quicker buck, do what BTB suggests, abuse ToS of different platforms or create something that has value in the long run.
My initial money was from abusing ToS and we were very good at it in terms of revenue. But we were young and thought that why bother with pennies and then things got darker and we began doing stuff on the other side of the law. Obviously, I'm not gonna share what it was or how it went, but long story short, someone in our team left a footprint, got caught, we got linked together and it cost me pretty penny to get away with everything ( I'm not from US, so laws are bendable with enough money and connections ). And it was online based business for US market. Had to stay low for a while, had to ditch the team and, believe me, the consequences are usually worse than what you think they are.
Point of the story - you are only 16, you are definitely not as smart as you think you are and should you go that route, you will definitely make mistakes at one point or another. Especially if you can't manage growth properly. Growing too fast is just as damaging as not growing at all from my experience.
Take your time, learn something useful for the long run and don't get caught up with all that Walter White bullshit. It's not as glamorous as people might think.
