Which exchange is trading BTCQ now ?
You can look at the roadmap, when will they try to get the coin listed on exchange?
Why you ask for it anyway? Want to sell what you got from the airdrop or want to buy more BTCQ? If you want to buy then you can join the crowdsale or open an offer to buy BTCQ, maybe there are some user who are willing to sell what they got from the airdrop for quick cash.
