Wow it looks easy to add it, given that we can have almost instantly 700 votes

.
The problem is not to add but to have decent volume over there. Who will move and trade on that humble exchange? The question remains to be a rhetorical one.
Anyway, it's possible to be added there almost without taking time from devs. We need just to do vote for MNX. I think it's easy to get few thousands voices there from our community
It will do more harm than good. That exchange is still out of work. If MNX is listed and not traded it may be undermined . Do not see any sense to cast my vote.
