BQQQ is not available on Bittrex, for the reason that it is not yet in trade to the main pairs (ETH? BTC) on the Bitsdaq Exchange itself. I think so.
As mentioned above in a post about support from Bittrex - I do not think that listing on Bittrex will greatly affect the price of BQQQ.
Bittrex is now not a very popular exchange itself, with a bunch of restrictions and they are going to tighten the passage of KYC, which will also have a negative impact on trading volumes.
