I would invest it. Every year, I would withdraw the profits, so that my net worth stayed approximately the same.

I would throw an event in a different city each year.

I would get that money ("earned" from doing nothing more than investing it) IN CASH.

All the cash would be loaded up in a plane and dropped in a public place. It would be a spectacle. No advertising needed, word of mouth and social media would be more than enough.

At each event, I would remind people that the money dropping from the sky is merely the crumbs from a single billionaire. Money that I did not earn. Money that was taken from the fruits of their labor and added to my stock portfolio.

I would ask them to imagine how much more money billionaires are hoarding. I would then bid them a fond farewell until next year.

Oh, and also, maybe a nice condo in southeast Asia. Thailand, maybe. Somewhere chill and fairly inexpensive. Not because I deserve a nicer place, but because fuckyouallI'mrichbitchstillnotatotaldickheadthough.
