I think that they plan listing but they does not know when this listing will be

It is imposible to develop project without listing.
of course because if only the project development without listing of course it will make investors bored and will throw away tokens maybe in forkdelta or other markets that are not official exchanges
At Forkdelt, selling coins of this project is simply pointless; my 55,000 coins are worth just a few cents.

Forkdelta is not a good place to sell tokens. It is necessary to have listing on a big exchange. Only in such case the price of tokens will be good.
