we are alive. development is ongoing. i've lost count of how many times this has been said. other coins develop,they don't keep announcing every stage. when we have something to release we will let you all know. the mixer tech is very complicated and will take time to get right. no point releasing something that crashes as soon as you use it
I hope that what you said is true. If you are still alive, what you should do now is to maintain an active state. In fact, listing more exchanges may not be effective, at least for privcycoin, listing more. The exchange can only lead to more dumping, so this does not have much effect. I suggest you start a new round of signature rewards and think of an attractive model.
