You think you would get to live in the same place with no one knowing you won the $1B lottery? Interesting.

Me, I would go to a top law firm and see a senior partner about getting out of being publicized. Have them set up sale of property and disconnect my phone lines and internet accounts after creating new unknown ones. I would have the lawyers present the ticket for me through various layers of holding companies and trusts, but I would be a ghost for awhile. The legal team would make sure all family members got some money with a nice non disclosure agreement. Immediate family would have my contact information with a request to never disclose. All money Would be dispersed between several low fee brokerages where I would invest in a combination of treasury backed securities, short term CDs, total stock market ETFs, and cash would be dispersed between several high interest savings accounts. I would be unreachable for 6 months while News died down.
