Let's say you win 30 mil or even 5 mil in the lottery, where would you cash your check? The bank? How would a bank hold that amount of money? What if the bank goes down? They say only $250,000 is given back

.FDIC government insurance only covers up to $250,000 account balance in the event of a bank failure. Some would use multiple banks to cover their savings.

I suppose one would use managed investment funds to earn higher interest, though it's a big enough amount to have your own investment manager.

There are What To Do If You Win the Lottery articles, also discussing lifestyle, as well as money management issues, a surprising number of winners in up less happy and more broke in just a few years.

You only put the amount of money into a bank that the FDIC will insure. The rest goes into another bank. The best thing you can do...should you or I win...is get a very good financial adviser. Your biggest problem is not where to put it but how to avoid taxes.

A steel vault is good. It's really protective and no one can steal your money. If you won 30 or 5 million dollars, you should be able to own a steel vault. Just sayin :P

I have about 1 mil plus. I put it in around 20 different places. Banks, properties, stock markets, gold etc... you gotta diversify.

under your mattress!
