If you look at their GitHub, all activity was there 2 months ago and that was probably when the so-called coin was launched. After that, nothing at all. If the owners can abandon the coin, then why not you?
Come on dude, learn something to earn. Do you really believe you can hit a fortune just by creating a coin for a few dollars?
