GTA VI needs a few charities.

I just broke the $20 million in the bank Milestone which might not seem like a lot, but in the years pursuit of owning the fastest, finest the most luxurious of everything... Two mansions in fact, one for the location and one to overlook my luxurious yacht, basically owning every great and expensive thing in the game I don't have anything to spend money on. Yesterday I bought and completely upgraded another Hellcat just to change the color on the second. Anyone else have this problem, and ideas of what to do next?
