Tried to approach Bittrex and will tell what I can get from them.
I can imagine their reply, if any, as according to their policy they do not have to provide one.
Something like: "Dear Joe, your average volume for the past 6 months is 0.1 BTC per day and we also haven't seen any roadmap updates, new features or any other kind of update during 2018. Good luck in your future endeavors!"
Actually Bittrix have been willing to work with low volume coins in not de-listing if the Developers are responsive enough to Bittrix communications and have an active community.
If not, I'm sure the other exchanges will welcome the extra volume...
