I am not aware of Yup being traded on any exchange (anyone else?).  What we really need is to arrange a community takeover.  I don't want to do this myself though, as while I can do some coding and perhaps port patches, I'd prefer someone else to take primary development lead and I definitely don't want to be the project leader.  Once we have released an updated wallet (this may involve some pain for those on forks losing their staking/masternode rewards for the time they were on that fork), then we can start to look to get listed on more than one exchange.
