From what you said, I picked few points, first is the difference in price from when it was listed to now, and the difference is quite much. Secondly you said it has been crashing ever since and probably the team aren't doing anything about it or they are, never can tell. However, from my own opinion, I can say, if the price of a coin keeps crashing and shows no signs that the team are actually working on it to improve, then it's time to move on. Also, about what I think in terms of the coin as a whole, left for me, I would focus on other coins that have the chances to grow always, thus starting from BTC and major altcoins.
