You got to thing more through if you have won that kind of money.
Singing on the spot isn't always a good idea.
I would roughly do it this way....
1. Take a photo and video of yourself holding the lottery ticket and put away that lotto and the camera in a different places like in a different bank deposit boxes.
1A. Take a deep breath and think about this you have like 6 months or 1 year to collect this.
1B. Try to act normal and do not talk to anyone about the winning.
2. Think about who you want to share this new found wealth.
3. Go to several large tax/law firms and wealth manager and consult on remaining somewhat hidden, implication on sharing money and best possible option to put away some of the winning.
4. Go the the bank with your trust ones and or lawyers after everything seem sorted out.
5. Go collect wearing clown makeup with big sunglasses on.
6. Go on a long vacation and think about in which foundation should I create to help out those in need.
It's kinda fun...
Too bad I didn't win....
If I was in state last week and I would've won instead of that guy...
