Forget the lawyer/accountants.
That's a really REALLY bad idea. First of all, putting all your money in one bank is idiotic. That's called "putting all your eggs in one basket." That bank may fail. Your deposits are only insured by FDIC to something like $100,000. You do the math.
Second, inflation will kill the value of that money over time.
Third, you're still spending a TON in taxes.
Fourth, you have no protection of your assets against creditors. You get into a fatal motor vehicle accident (they happen), and kiss that entire nest egg good-bye.
Fifth, you have no way to give any of that money to anyone you care about without the gift being taxed by Uncle Sam and the states. Got kids or siblings or nephews/nieces or just friends you want to help? Get ready to pay the tax man.
Sixth, whatever you may have left when you die will again get heavily taxed. Your heirs will get only pennies on the dollar compared to your original winnings.
Rich people use lawyers, accountants and professional money managers for a reason -- they work. When you have that much money at stake, it's worth it to spend a few hundred grand a year to people who know how to protect you.
