I think it’s really hard to speculate about something that’s unimaginable.
I don’t think I’d want that much money, as it would mean a drastic change in my life. My daughter would be a kidnapping threat, etc.
If I did have that much money, I’d first make some relatives who are in the financial field my advisors. I’d also give them a big chunk each. Maybe two million each.
I’d create (with my financial advisor team) some type of fund so the money would be out of my hands, personally. I wouldn’t want to be threatened with lawsuits, as does happen with wealthy people, so the money would be tied up, legally, in some other way. I’d of course give big chunks of money to those that are close to me – several really good friends.
After that, I’d probably plan to travel and have a house or two, and do some philanthropy and other charity work. I am really into animals (stray cats, animal rescue) so I’d do some volunteering in some way with that, and donation of money to those types of places.
