The cryptocurrency revolution is a revolution on a global scale. Maybe we also need a local economy revolution? Local currencies have shown to be a useful complement to the monetary system that is in use today. Many of the local currencies that is in use today have a limited time of use which takes away the urge to save them. Another benefit of local currencies is that they are local and therefore drive trade towards local businesses.
