Your own idea of what you'd do is actually brilliant! Damn.

For me it would simply be teleportation. With teleportation I can be in and out of vaults a million times in a day. I wouldn't be robbing no good people, though, I'd just rob drug kingpins, corrupt politicians, etc. There are too many bad people to rob.

By the end of 24 hrs I'd have trillions of dollars. And a clear happy bubbling conscience 🙃
