The value of a particular token doesn't always increase just because their is an increase in platform adoption. I think this is a common misconception in the cryptosphere at the moment.
That being said, I think the first use you've described - where the coin is a means of promoting listings - is a good example of the potential appreciation of the coin over time. I'm less convinced about the other uses resulting in an appreciation in coin value.
Still, a great project and I'll follow the success of the app. Thanks for the post!
