An interesting question, I would probably immediately buy a house and a new car, as well as gifts for all my relatives. Of course, it still depends on how much I won, if a couple of million, then I would spend almost every day on what I wanted, if less, then I saved, but I never worked. I, by the way, play in the casino very often and saw how people hit the jackpot, I wonder how they spent their money? I've seen this on many sites, and even a friend of mine once won a large sum of money here
