I'm not sure where I should send the requests about updates telling the truth. And if devs even check something like that. A lot of time had passed since they added the last coin, so I don't think they work in this direction. As only other features are improving now.
In any case, there are other exchanges. You can always use them as extras. In principle, at the moment I do not need additional coins. I am quite satisfied with the existing set of coins.
