If any of you trade on this or the Bittrex platform I would suggest pulling your money right away. For exchanges I use Cryptopia or Poloniex and NEVER suggest you keep more than you are trading in your exchange wallet. Decentralized exchanges are coming soon unfortunately things like this are a part of the process.
