Just to update. I was able to get my coins. Kucoin support was helpful and timely in assisting me.
I also changed the title of this thread from "Kucoin stole my Polymath?" to "Kucoin delisted Polymath", because the first one may imply deceit.
Its alright, but you just have to try as much as possible to make sure you do your finding and get your fact right before you make any negative utterance about people and projects, these is how majority of us has killed some business because of our little impatience, and know people generally in this forum and other forum Likes to follow trend without making their own findings to confirm the accusation before joining in condemning too. I am glad they were able to resolve your problem and I am sure you will still continue to use them because they are good and reliable exchange too.
