In order for the token to be decently valuable in the long run, there must be sufficient demand for it but that is not what is usually seen in the ICOs. What is seen is unsustainable token inflation which largely happens because of flawed economic models and the greater fool theory (more on that in a bit). Endchain are going to destroy more of its coins if the current market value of the coin is low, so it  is undoubtedly trustworthy.
