"exchange working" hmm are you sure you have the right coin? couple of coins out there with similar symbol have folks confused! Potential buyers who want to setup masternodes, goes to the exchange buys das then tries to withdraw and gets the maintenance message. which as been happening for 3 weeks. then they turn around and dump it to cut their losses and get back their bitcoin. one of the reasons the price is down so much. again are you sure u have the right coin and  exchange?  o btw I dont think this is an exchange issue, all the problems the community is having with the dev and this coin I could picture him telling the exchange to take the wallet offline till further notice. to prevent folks from depositing and selling. good for you that your mn's for this coin are working!
