It seems Poloniex is gone as most of people aren't able to withdrawal their funds.
Once one make a withdrawal it will be sent to "Awaiting Approval" and there stays forever.
you will find in Twitter, facebook, forums, etc that people are awaiting over 20-30 days without any answer from the support team.
Some say who has high limits account (verified) aren't having problems but I can't confirm that.
Pennies withdrawal also might go through however anything above 0.1-0.2 BTC will be stuck in the "Awaiting Approval"
Do you do Poloniex?? Then go ahead and try withdrawal 0.2 BTC to find out.
Good luck.
IDEM 0,026 BTC .... 48 hour but not whitdrawal
