Stay anonymous
Although some lotteries permit winners to stay anonymous, usually, people are eager to show off and brag about their money.
If you automatically start buying fancy clothes, driving luxurious cars, and giving money to your friends when you come into a lot of money, it’s pretty transparent. More often than not, people who notice that somebody they know has gotten their hands on new things will try to blackmail them for some of it–which inevitably causes conflict.
