The WINGS tokens have not been created yet, therefore it is not possible to transfer, withdraw or trade the tokens at the moment. We are in contact with all major exchanges and will update once we have any news.
WINGS tokens are scheduled to be released around March 2017. At this time, the WINGS tokens will be created and allocated by the smart contract, which means that they can then be added to exchanges that wish to feature WINGS token trading.
It has also come to our attention that the exchange Liqui has launched an I.O.U market for the WINGS token (tokens there are not "real"). This means that the exchange has participated in the WINGS donation campaign and is currently trading it's own tokens that have not yet been created and allocated.
