Some generic advice
Savings accounts are really bad investments and they barely outpace inflation. You'll earn much more if you let a mutual fund invest your money. At the very least, invest in US treasury bonds.
You will never earn money by investing in precious metals, only slowly lose it. It's hedge against what you think will be a catastrophic market crash, not an income generating investment.
Once people find out you're rich (and it's only a matter of time, it's difficult to hide wealth even if you don't flaunt it) thousands of people will try to contact you begging you to invest in their charity or to pay for their sick family member's life-saving operation. Most of these will be scams.
What would I do?
I'd pay off my parent's house and give them a big annuity to do whatever they'd like. Same for my grandparents and cousins.
Hire a construction company to custom build me a nice home near the ocean. Buy up plots of land surrounding the home.
I collect firearms so I'd buy stuff I currently can't afford. I'd build my own range on the aforementioned land.
I practice archery as well so I'd dedicate more time into that.
I would support amateur artists I like by buying prints and paintings off them and commissioning artwork.
I think I would learn how to fly, I've always liked the idea of being an amateur pilot.
