@everyone any Poloniex questions need to be directed at the owners of the Poloniex exchange and not here.  Poloniex delisted XDN awhile back and was offering withdrawals at the time but you need to contact the exchange to resolve those issues that are separate from the main XDN project.  Poloniex has been relatively silent about this issue but it is solely in their hands (I also have some XDN stuck on the exchange still).
