Which delta? ETD or Forkdelta? If you mean Fork I think that you were wrong cause only ETD is going to die and there are no traders and investors wanna use ETD to trade anymore cause it's not a safe place to trade so nobody wanna put their cryptocurrency in risk by using this exchange anymore although they can sell every token as they want on this exchange 
Of course we are talking about ETD. Forkdelta in good condition. I do not understand what can be a reference in a decentralized exchange? I use the ETD de lait still and have no problem, tell me why it is not safe?
