In a way, I guess all of them have utility , but the question is on who exactly can utilize them. Not many coins I feel will have much interaction between 2 users beyond simply buying and selling in attempt to generate profit. It's kind of cool to use them in a way beyond this typical model. I am really excited to see where the next couple years will bring us, because I feel that our world will not only be filled upon these styles of coins, but actually shortly after, dependent. I keep telling people that a world outside of their scope is developing and is going to completely change the way we live and interact. The development will be very interesting indeed.
