If you have unlimited money, what's the first thing you will do?

I would donate it, use the money to help out my family and friends, and start a cat cafe.

I will buy a big house and make a gaming place with all console, a gaming PC and an other room with a really good sound system with a bar for party

Help out my family. Basically give them money so they can pay the rent, as well as the debt stuff, what about you OP?

the first thing i would do is buy a house. then i'd probably buy some hookers and a mountain of cocaine.

figure out why i have unlimited money - otherwise yeah you would probably want to spend your money like bill gates - giving back etc

Pay off all my bills & buy a car. Followed by a new computer and house.

A house , a car and food. .

Well since it's unlimited money, i would of course give quite a large sum of money to my family (Who would'nt).
And if im gonna be completely honest here... I am one to believe in the inevitability of a nuclear fallout.
So thats why i would buy a large plot of land in the North-Eastern part of Nevada, where it's a good distance from large cities and ocean.
Then i would build a whole bunker system of barracs and halls, not to speak of shooting ranges, to be able to keep my little society of friends and qualified.

Help my friends and family start their dream business. Even unlimited, the best idea I have heard is to ask your friends/family for business plans then invest in them. That way you both win if it takes off.

Buy a house and bankroll some of my friends project ideas. Live modestly with a few small dogs.
