First of all, I was very indecisive. It is crazy to have that much money. I used to buy the fastest cars in the world. I would change them as I got bored. After that, I would buy a 1969 mustang and drive it. I think it would be very enjoyable.
i will buy super high end computer in the world and i will pay the computer genius in the world to make me cheat cannot be detected ever even if i died .
also pay the scientist to invent ways to slow down aging or immortality would be best
