At the mean time we can only wait. I emailed support and got the following response:
Hello,
STEEM withdrawal is suspended currently because of wallet maintenance.
Please kindly wait with patience.
Thank you for your continued patronage.
Sincerely,
The Binance Support Team
I checked the binance steem account and last activity was 7 days ago. https://steemit.com/@binance-hot/transfers
Let's wait for a week or two long, if I cant withdraw then, I'd probably convert to other coins like DASH and send DASH for steem on blocktrades.
