Well they paid for it and in time it will get listed on Cryptopia. If you would bother reading you would know that Cryptopia is currently working on more urgent matters. An official rep adressed the issue on their reddit and said that listing Colx isn't a priority. They first need to solve the wallet and plattform issues and have a huge backlog with regard to support tickets. By the way they are pretty pissed since it seems a lot of Colx holders are spamming their mailbox with "when get we listed?" mails. They literally said if one more email of this kind arrives they will move the listing down to the bottom of their priority list.
