In my country the name of the winner of a lottery is not publicly announced, they just say [X] number of people got the numbers rights and will be receiving [X] amount of money. From that onwards I think they have three months to pickup their money from any lottery house. I've seen a lot of threads and videos on what to do if you win the lottery in USA, but because the name of the winner is kept private a lot of things here would be different. But I would still assume someone working for the lottery house would leak my name. Also, my bank would be the first to known I have that much of money now and would try to push a lot of things for me (investments, premium account etc).
But, if it me winning the lottery here, the first thing I would do is not pick the money right away. I would let it pass a month or so until no major news is talking about it anymore. I would get myself a financial advisor, and I heard you have to hire one from a big firm because the backlash of one of theirs scamming you would be a bad PR for their firm. I would get my money from a lottery house far away fro where I live, and choose the small payment option over withdrawing the entire sum all at once. I won't get the entire money for myself, but it would be easier to control little money than big money, and interest rates would let that money growing a little over the years.
I'm single right now, no family of my own, and I don't have many friends, so no big party for me. I would keep my mouth shut and keep living like nothing happened. I would like to invest part of the money in something conservative, so I can cash in years or decades later. I'm 27 now, have a good relationship with parents and my own house, so no need to worry about having big money now. After that I would... just live normally. Probably pay for medical exams for my aging mom, any other debt we might have, renovate our house etc. Buy an apartment or land far away where I live, so I can have my own place, maybe rent for someone else and have another monthly influx of money. After some time, say a year, move from my house to said apartment far away from the neighborhood and people who might know me. Say I just got a good job offer.
Yes, I would travel, visit the State where I was born, and enjoy games and good food, but trying not to blow up my money on stupid things. And If I got a partner, I wouldn't tell her I'm a lottery winner, at least not until enough time has passed. Maybe just lie a little and say I have old investments that are paying up now. Ah, and I would move my mom from her house to somewhere else, where she can rest and be safe, and not having to worry about having to work another day of her life again.
