So what makes you finally give up on a coin, if anything?  I know I have some coins that seem to be dead but every now and then, some life gets pumped back into them.  Of course if the developer stops working on it at all, I think that is no good but I just wanted to see what some others consider to be a lost cause.

Would definitely love to hear from some that have been in the game a while but of course I will appreciate everyone's opinion.
