Id cap it at $10 million. I legitimately cant find a non-philanthropic use for $10 million.
Some quick napkin math says i can spend about $1.7 million before running out of ideas to spend money on. Thats a 4b/2ba house, replacement car, backup car, house mods, gifts for family/friends, and a giant fuck you overkill server rack build for whatever tech projects i want.
Put the rest in a garbage, basic ass savings fund and im already making more passively than i do manually now. I could blow $2k a day on literally anything and still make money.
