The coin is still able to be mined, and is trading on Cryptsy. So with a dev or not, there is value there... I personally think it is cool how the block rewards are variable while following the earthly cycles.
Anyways, long story short, I have added Earthcoin to our pool. Please feel free to drop by and either mine it directly or use the profit switcher. I'm running a NOMP portal, with some very minor modifications. Shoot me a PM with questions.
Also, our team (
http://www.revivalco.in/) does coin revivals. Please PM me and let me know if you support this type of action here.
