This is an idea started by Marcel with his Project 33. While it is a great idea, does it really work? Like anything that can be traded, it can have a value-added to it as long as the community agrees. So far it is working. BUT, can it be used by anyone for anything, NOPE. So, while the idea is great, we do not see this being a thing for the real world. Only money really allows you to trade freely to get what you need.
