The world is changing with each passing second. Has there ever been a time of uncertainty and prosperity? Artificial Intelligence will either make our lives easier or destroy humanity. Thankfully, we won't be delving into that topic.

Just twenty years ago, buying something was very easy. Consumers carried cash, dollars, quarters, and even pennies. Cash is now one option when buying and selling things. The state of Idaho recently passed a law guaranteeing that cash will always be used in commerce in the Gem State.
