One of the reason why I am so interested in this project is the fact that holders of PTM will not only own a particular number of currency units. The PTM apart from being a unit of exchange, is a stake in the future success of the entire network for a stronger community which is like loyalty program.
Of-cause I do agree with you, when users are given the opportunity to become part of a project via holding PTM, is gives a sense of belonging and holders would prefer to hold which is a good economics of the potentiam structure.
