I cant agree more. According to the Gamification theory . Points is a very important part of incentive mechanism . But traditional points have many problem For example , the use just can use it at particular system , you can just spend the King berger points at King berger store .

But if we use the blockchain tech, these problems can be solved !
This is a very godd use case about blockchain tech ! And Waves platform can offering these service!
