And this is their answer:
Thanks for the request. Our policy is to not comment on whether we will launch coins but we mainly add coins due to community demand.
We gauge demand based off of tweets, hash power, length of bitcointalk thread, volume on other exchanges, etc. Follow us on twitter @bittrexexchange and tweet about how much you like this coin and Bittrex. We respond to creative and insightful posts to help market your favorite coins and Bittrex. I'd also consider coming to our irc channel #bittrex on irc.freenode.net and do some guerrilla marketing. The traders there can help you gain exposure for your coin.
Thanks,

Bittrex is not going to list drz if there is too much fud on thread. Community need to promote it as well as you can read by yourself.
Thanks
Off course.
DRZ have been killed by community,fudding every minutes, not from the dev.
Now community or investors need to push as much they can to be listed.
dev can't do nothing. It's just a community case.
