Well, it's been a bit too long, but I'm going to clarify this anyway.
There is CNX coin that is traded at HitBtc and ERC20 CNX token that was airdropped to random addresses and has no particular value as of now. It's a bit confusing since they've got the same abbreviation, but I hope you understan. Etherdelta has listed this token without Cryptonex's approval, and then denied all the requests to delist it, but you can still drop this tokens there if so you wish, it'll be like 6 bucks worth of ETH or something like that. Still, I'll highly suggest you wait for the next bounty campaign where you will be able to trade this tokens for the CNX coins at a certain rate that will be announce later, given that you haven't got rid of them until now
