Actually, up till now, I still don't understand the activities of this exchange.
CryptalDash exchange is a Ukraine based exchange with its headquarters in Estonia. It was founded in 2016 by Amine Lahrib. I wasn't able to find enough information about the exchange on its website so i had to do some extra research, that was when I was able to expand my findings.
CryptalDash exchange allows traders to trade with a minimal fee of 0.1% for both parties, makers and takers. There's a discount that comes with this fees only if you trade with the exchange's native token, CRD. I don't think this exchange offers any trading services anymore and as such, it has been recording a daily trading volume of $0. The twitter account is no longer in existence while the telegram group has merely up to 90 members.
