I don't use Cryptsy so I can't promise that a trade key will work.. but will check it out. Otherwise, a regular old btc wallet address is your best bet :) thanks!
Trade keys are great! say we both use cryptsy, I give you my trade key. it's like an all in one wallet address. So you could send me Zeitcoin,Dogecoin,Bitcoin anything at all to that one address---the deposit sorts itself out no matter what coin it is---if you ever get on and feel like donating please send "whatevercoin" to: 8a9dcd1f970be72d47d6f78c3dd83f2899629043 <---trade key great auction
