GUYS NOVAEXCHANGE IS CLOSING TO NEW MANAGEMENT SO IF YOU HAVE ANY OLD ETHD BE SURE TO WITHDRAWAL IT TO ANOTHER EXCHANGE.
I received an email. They will be back next year with a new management but they will stop trading engines and all the money left will be considered donations.
its to better handle scaling, stability and security. anyway advice to ETHD holders would have transfer their ETHD if any,I think theres still quite a large amount of ethd being traded on nova at the moment!
