It is true when you receive such a large amount of money, the change is brutal and it is difficult to react appropriately. Even to spend money you have to learn. But I think it's more of a character thing. To do what you want more than what they incite you to do, that way it is difficult to have problems.
Although I must say that if you receive 2,000 million dollars I see it very difficult to end up in ruin, you have to do things really badly. Although it is certainly not impossible.
You'd have to be pretty bad with money for sure!! :D
