Suppose you win 100 million. What do you actually do with it? Banks only guarantee 250,000. Do you have to invest it? Is there anywhere you can just let it sit and draw interest?
If you have any decency, get rid of most of it, preferably to charities or political causes.
That sort of wealth in the hands of a single person is obscene, and spending it on luxury when there are people starving and homeless in the world is the height of immorality.
My partner worked in non-profits for years. Her advice is find local organizations (homeless shelters, local LGBT orgs, neighborhood revitalization orgs, ect.) that DO NOT have a national (central) office. Get to know their staff, their mission, and then make pledges to pay $X per month for the next X years. This is how they can best do the work they are passionate about to help people in need. Don't put strings on the money and you are moving closer to mutual aid than tyranny.
