Non fungible tokens are really innovative. I don't know though how reputation is going to be increased if more users join the platform. Would the supply increase after a specific amount of registrations?
I am not an expert but I think that two things may happen. a) The token supply will be increased in a necessary amount of users is going to be reached b) It would be hard to acquire non fungible tokens as the number of users are increased (this will also increase competition among the developers)
