I still find just the fact scary that at this moment automated systems are shoving billions of fake money back and forth around the world.

Unless you barter your groceries you are using "fake money" every day.

How is it fake?

Or better call it virtual money. (but we all know theres also "fake" money made and destroyed in that system, too)

As opposed to all the "real" money in the world?

How is it "real"?
