To tie the concepts of optimization and yield together as it refers to currency we need to understand the need for money. Without some form of money we would have no way to trade. Without trade we would have no commerce and without commerce we would have no way to better our station in life. Betterment of our situation is as fundamental to the human condition as breathing – we all want to succeed and make a better life for our communities (communities of family, friends, neighbours, countrymen, etc.). Therefore the faster we can make money move the more opportunity we have to profit from that movement.
