Poloniex - STEEM/SBD
STEEM is currently under maintenance or experiencing wallet/network issues. Deposits and withdrawals will remain disabled until a solution is found, which may require an update from the STEEM team. Any updates must be tested and audited before enabling.
^^ Think this will ever be fixed ?
Up to them and unfortunately, there's poor to no communication with them regarding any issues, not only STEEM/SBD related.
As mentioned before I offered my help to Poloniex over two months ago. No reply. Ticket is still "being processed".
It really takes 60 minutes to setup and less than 6 hours for resync on anything other than potato-grade system.
They have been having problems for a long time. Best not to use Poloniex for Steem right now. Bittrex and Kraken may be better options.
