I just opened a support ticket in Poloniex and I got this automatic reply:
Information About Deposit Delay
Dear Jose ,
I am very sorry to inform you that we are currently experiencing a momentary problem with the wallet and had to disable it for maintenance.
As soon as the wallet is re enabled your deposit will credit.
Thank you for your patience and I am sorry for the inconvenience, don’t hesitate to reply to this message if you have any question.
Sincerely,
Poloniex Support Team
It could maybe take a while but let's hope they will fix this issue and everyone will get their funds back.
Meanwhile let's keep steeming 😁
