you donot like bittrex then donot trade there.
But take a fair advise.
Run run very very hard away from ploniex as soon as possible.
Donot just take my word.

Do just 3steps.
1.Withdraw your bitcoin to a local wallet from poloniex.
2.Freezz poloniex account .
3.Book a support ticket to unlock your account.(Say them that you observed some suspicious activity so you freez your account on the 1st place)

Now you will see the game begun.

Wait to 1-2 years I donot think after that also you will get a reply from support.(People are waiting for 11-12 months)

Just try it.thank me later.
