they were supposed to be added there, but it seems OKEx claimed to put them in listing queue and didn't provide updates ever since. I woud love to see them on some of the larger exchanges too. That would help its trading volume and price
to add to the stock exchange need money, and where to take them to the developers ? The first is the ICO, but its not the case !!! The second is to sell the coins produced during the testing of the network, but there is a failure...while mined, the rate collapsed traders who are not interested in technology... It remains only to hope that the developers have their own money for the listing !!! Otherwise, death at birth...the team needs a good marketing expert
