I don't have much more to say about it, but as I made a number of posts about the situation over the last few months I thought I would update my followers.
Backround
On the 19th of June Poloniex took their STEEM and SBD wallets offline with no notice.
On the 5th of July withdrawals and deposits were brought back online for 8 days until the 14th.
At this point this message appeared
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.
This despite Bittrex, 
The wallet was again brought back online for the period of the 21st to the 26th.
And then one last time from 3rd of august to the 6th of august.
It then remained down until today 20th of september.
It is very possible the wallet will come down again so withdraw now while you can
Arbitrage Opportunity
I posted about an arbitrage opportunity where for the last month you could sell your STEEM for btc transfer to Poloniex and buy STEEM at a 10%-20% discount. Today that arbitrage finally closed returning about 15% returns for 1 month.
The risk of course was Poloniex not returning funds, I maintained that poloniex have shown themselves to be incompetent, not thieves. Not much better I know.
