That little amount of money isn't even enough to make me dream. I'd likely just put it in my account and not care much about it either way. It's something nice to have, but not life changing. You'd have to add at least four zeroes. With ten billion in paper money I could do some basic dreaming. Still not enough for big dreams, but it would be a start.

I'd invest in the creation of an anime studio in Japan that would churn out all the anime I want that nobody makes. It would likely cost a couple of million per series and I'd want hundreds of them.

But yeah, with just some pocket change, I wouldn't do anything.
