I have been acumulating Steem and steem dollars in Poloniex and for some reason they have stopped withdrawing . I tried
to send it out to another Wallet and It was stuck in their system for a few weeks. Finally I found it in transactions and cancelled
the transfer. It has now been credited back to my Poloniex wallet.
They have a Notice "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.
Hope they will hurry, I am 80 and could croak any day.
