It is still listed: https://coinmarketcap.com/exchanges/etherdelta/

Since Etherdelta seems to the frequently offline, I think that is the primary reason why it is currently listed as inactive. Also, recently there has been numerous reports of Etherdelta's API not working properly.

The Etherdelta coin isn't listed also, because it is only traded on etherdelta at the moment and that is not listed.

The site itself seem to be accessible once again. Not sure what's going on.
