I wouldn't advise anyone to take that risk. Even if OP is serious this is a bad decision for both parties. Cryptsy accounts had several levels of authentication that would allow OP to get the acocunt back even after the "buyer" would get full access.
Agreed, doesn't Cryptsy allow transfer of funds between users at no charge? I can't recall it has been a long time since I used Cryptsy.
Yes. It could be done with a trade key.
And OP is a kid telling that all ge can give for 35btc is loggin name. For that amount bro you would need to give at least your id to scan it and a signature in the eyes of a lawyer to make sure you will not try to claim it back. Sonif you are trying to scam, sorry, to sell, account details for 35btc and step away so this would never happen.
Try offering your account to your own friends that trust you and later split the money or whatever. But trying to sell something that couldnt be even described is a big big NO.
You knocking wrong doors
