This thought occurred to me the other day, as the sales of the stuff packages have led to a little buildup of money in my Paypal account that I have not yet converted to actual folding money. How much money sits in the Paypal system in steady state? They charge for some of their services, but I wonder how much money they make from the interest on the float of the cash that sits in their system before you take it out. If you have 10 million users that have an average of $100 sitting in their accounts, that’s a billion dollars. Now you are starting to talk about real money, kids.
