NovaExchange zeitcoin trading is still blocked, but the wallets were allowing withdrawals
(No reply back yet on when it will be fixed.)
recommend moving all of your zeitcoins to one of the above exchanges that are working normally until they fix their trading bug.
Yobit (Do Not Use Yobit) : Wallets do not accept deposits or withdrawals for over a year 
FYI:
Question for the community, at what time frame should we place them on the Do not Trade List like yobit , if they are not allowing deposits or withdrawals to their zeit wallet.
Time frame choices.
1 month of being offline
3 months of being offline
6 months of being offline
Wanted to see the community's feedback on the above question.
