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.
