Honestly, it has more to do with how I would feel about that money. Getting something like this without a real effort would make me feel very empty. So, realistically speaking, I would save enough to live a normal life, investing in a small self-sufficient business and not telling anybody about the money. Of course, coming from a Not first-world country, I would spend most of it to get my whole family out of my country. And the rest would go to charity.
