I don't understand why people are confused on how a utility token works. From my reading of it, MEDX will be similar to most alt coins out there. MEDX is the "currency" that is required (whether on back end or front end) to purchase medical diagnosis on their app. As a token buyer, you get the token at a (potentially) lower price than what could be possible further down the line as the platform expands and demand for services (and therefore demand for medx) on the app increases. As a token holder you could then sell the tokens to those who need the medical service on the app
