I still have a pending case with COSS exchange, I made a deposit and the deposit never showed in my COSS account,. This was in 2018 and when I wrote to support, after taking a very long time to respond, they still didn't resolve the issue up till today, I would rather throw a token away than trade it in COSS exchange, that's how much I dislike it.
Lol, I have some of their coin anyway and I am waiting for bull run to terminate my deal with them also, because I don't see coss as a serious exchange because they are not new, they have been in existence and majority of those other exchanges that have come after them are doing perfectly well, but I think that their team is actually too weak to drive this project somewhere, they dont want to move forward and get some real volume on their exchange and without that, there is no way that their token can grow naturally.
I am just waiting for the opportunity of bull run to bring out my investment which it is still painful right now, that I actually invested so much in this childish project that I believed in so much. I wish that it was even possible that I change my coin to bitcoin.
