Hmm what I would do with 300 million dollars?
1) Purchase a new car, more then likely a BMW ($47,440).
2) Purchase a plot of land, 5-10 acres in size ($200,000 - $500,000).
3) Have a nice 3 bedroom, 3000 square foot house built on that land (TBD).
4) Purchase an Internet line straight from the backbone provider and have it run straight to my house (TBD).
5) Build the computers and servers I've been wanting to build for a while now (Roughly $8,000).
6) Deposit 50,000 into my checking account.
7) Create 9 savings accounts, along side my currently existing one, and deposit 50 Million (5 million per account).

Pay off the two loans I currently have.
9) Place 20 million in several high Interest, high security, CD's.
10) Invest 50 milllion in stocks with varying different companies.
Making estimates on the TBD prices I've spent $121,121,500 spent so far, with most of it being in ways to save and make more. This leaves me with $178,878,500 left. Out of that I would probably use to help my family eliminate their debt and leave them with $100,000 extra. The rest would more then likely be donated to various different charities.
