I have some kind of coin in my eth wallet, but I do not have ethereum to be my coin sale fee
how can i sell my coin without fee?
Fee is mandatory on ethereum network. Without fee, you couldn't transfer your ether balance to any address, nor you can use it on etherdelta.
To initiate a transaction through ethereum network, you need to first acquire gas. Gas is an internal property of ether network and it gets converted internally.
You simply need to deposit minimum 0.001 ether in your account, only after that you will be able to utilize your tokens
