You can not do anything about it, it was your fault for only putting your money in that shitty exchange. We all know that using your own wallet for storing your coins is a MUST.
Your coins are lost now.
yes it is true that saving coins in personal wallet will be safer. in fact I never transfer my token to etherdelta if not to sell it because I am not sure about its security.
