There's positives to not having a listing:
-No extra emotions created by investors when price goes up or down, developer can focus on product with less disturbances
-Unable to buy it currently which will create a lot more demand if or when it is released - the price of the coin may sell much higher (instead of being smashed to bits on bittrex waiting for a product)
I'm sure there's more - could be why Majika didn't bother contacting Bittrex to keep it listed.
Could be a lot more work involved in AeroMe, could be the end.
My bet is that it's not and that there's more to come.
Coin might not survive for long this way. Someone has to maintain nodes, someone has to stake. If no update is given, people will lose faith and stop their wallets.
What other names does this Majika guy have? If he is experienced programmer working in crypto, he just cannot concentrate on a single project for so long (and probably he never did). If he is alive and still does programming, most probably he is involved with some other projects. This project is either suspended or is in background. I believe he will never resume work on this, even if he honestly thinks he will.
If he is honest man, he would come here for a moment, announce the end of this project, and offer his investors and believers a swap to one of his current projects. Honest and responsible people do that way. Scammers just disappear.
