Just get the seed phrase or private key and import it on another wallet that supports the QCX token. Hotbit can be used to exchange your QCX to eth for example. MAKE SURE you have enough eth for gas. Can you share what wallet did you use to store your QCX?. It is not easy to help of we don't know what wallet did you use. Since QCX used ethereum network then I assume you have the seed phrase or private key of your wallet and can be imported to metamask for example and then you can transfer it to an exchange if you want as long as you have enough ETH balance in the same wallet where your QCX is stored.
