Yep, this is the big one that we need - getting on Bittrex. A lot of people are asking for it, and it will make a major difference to the value of the coin. We can't expect any major increases in value until it's widely tradeable, with high liquidity on the bigger exchanges. I'm holding all of my BitcoinZ until it's on Poloniex, Bitfinex or, preferably, Bittrex.

Not sure what the barrier to entry on Bittrex is - but it could be that official devs need to submit requests. I know one of the users, can't remember his name right now, in this thread has done so already. The community can't help the Bittrex application directly, but can help by promoting the coin in general.
