Read this article carefully bittrex will keep disable deposit/withdraw of this coin for 24 hours so only those people will be to trade this coin who have their bitcoin on that exchange. I don't think there is early chance to get dumped from dev.
"At this time, the information and codebase presented by the Bitcoin Gold team is not in a functional state and Bittrex will not commit to opening a Bitcoin Gold trading market."
So till everything will be done correctly from BTG team end the pair BTC-BTG won't go live... while trades at others exchanges that supporting BTG will be live already. But I think BTG devs will make all by correct way till fork day.
