I bought this coin purely on speculation. The listing on Poloniex alone is worth 1 million market cap, possibly more. It would be nice if development can be picked up again. Else, you might want to consider selling the coin and its listing to someone else who can create fundamental value.
Yeah, I've done the same - there were some mentions above and on their twitter about being in conversation with developers in order to get this going again, however nothing for a few weeks. Looking at the coinmarketcap chart, its shocking to me that this coin has never had a market cap above where it is now (aside from a couple recent quick pumps), at $270,000 despite being listed on Polo. With a good idea/development this could increase in value very fast..
