Use the All-weather investment strategy to generate a neat return every year without worrying too much about a market crash. All weather strategy means something like: 80% index funds 12% bonds 8% gold/Cryptos

Do that with the $7M and you'll have around $350K every year (after taxes and inflation) for the rest of your life. And best of all, you'll still have $7M (+inflation) to give on to your own children when that day comes.

Your gift is my dream!

Altruistic: building a foundation to pardon medical debt, or tackle some low hanging fruit type problems in your neighborhood.

Pragmatic: Invest most in index funds, and use the proceeds to fund your startup.

Crazy: Alt-coins :D

Invest a third, give a third to charity, and enjoy a third traveling or doing other things that make you happy with the people you love.
