Neither CoinExchange or Yobit have yet to sync their wallet, making deposits and withdrawals impossible until they do.
Bug their support and chat rooms, if you want them to start.

At the present time, to actually buy and withdraw ZEIT to a local wallet , leaves SouthXchange, Alcurex, & Trade Satoshi.

Trade Satoshi is also suffering growing pains, so they are running very slow,

SouthXchange & Alcurex are running at normal speed.
