Granted this isn’t the most exciting of websites, it’s a sure time-waster. If you tracked every bill you’ve received, we could learn a lot about the money flow of this country. Or, if you’re not the learning type, you could at least know how many strippers have received your $1 as a tip.
After reading the highlights of the most traveled bills, you can waste more time by inputting every bill in your pocket, and even asking people around you to trade bills to input that data. After that’d one, hop over to the forums and meet equally bored people who like watching money move.
