I wouldn’t know.
If faced with such a crisis, I would set aside triple my max yearly income in my life, adjusted to current value and have that as immediate and liquid using standard familiar money holding things.
Then I would find out what kind of organization specifically handles such large funds safely for short periods of time (1-5 years max, with a goal of less than 1 year and no penalties)
Then I would take care of whatever irritations having 3x whatever my max yearly income in my life so far could handle until it was all spent.
As I close each of those old chapters out of my life being sure that they would also be taken care of for the rest of my life in whatever way is needed for that, I would also have half an eye to what’s being held aside.
I don’t believe I could answer that question until I got close to having taken care of, for life, all of the little and big irritations that that kind of money could handle.
I would hire who I would need to help in those tasks, but likely able to handle most of those myself as they would be within my existing knowledge sphere.
100 billion dollars simply isn’t.
The weight of current foibles would be replaced by the weight of the upcoming responsibility and at some point, I would have a clear enough head to consider what specific directions to take at that point.
