Has STEEM team commented on this message saying they do not know what Poloniex is talking about?
Otherwise, it could mean STEEM really has a issue don't you think?
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.
I really don't know what to think at this point I would just like to see it fixed by someone
Amen!
