Put it into offshore accounts and invest in grossing companies, whilst having trust funds for all my family members.

EDIT

I would move to a country where the taxes are really low and purchase my own private military.

I would give my parents some money to buy them a house and some extra stuff if they needed it and then i wouldn't buy something expensive just buy like a regular apartment and give some money to charity that what i would do if i had that kind of money

An incredibly nice house.

well if i had 450 million dollars i would first donate 50 million to different charities

then buy my family new houses and cars and anything they want and buy a 1967 chevrolet impala from supernatural ;) and meet the SPN cast then save the rest

I would honestly spend it on my family then w.e is left over have fun (;

I would by my mom and dad a huge house and nice car. Then I would help the rest of my family out. Finally, I would buy myself a nice house, a few cars, and then donate some money to charity and put the rest in a bank and let the money grow

First thing's first... I would put $250 million in the bank at 4% interest (at the least). I'd hope for better interest but I think 4% is pretty average.

Then I would take the remaining $200 million and buy a few houses in come gated community for me and my friends. I think I would look at Hilton Head Island in South Carolina. I would then buy an Aston Martin DB5, as well as a Rapide S and a Vanquish S. I don't know how much money I have left but it's basically all about them profits so I'd once again, get investing.

I plan on getting rich in my lifetime, and I am basically willing to achieve my dreams through any means necessary. My dream job is at apple corporate offices in Santa Clara Valley, California. I'll be in college for 8 years working on a double major in something in business, as well as computer science. Hopefully I'll get there one day and then I'll gift all the gold!

That would be nice to do donate 50 million.
