Please for your own safety, stay away from Poloniex. I was using polo for over 2 years, but they are doing really shady things right now (3 months unresolved critical tickets, refusing to refund anybody for their internal bugs when people got no open orders but still losing money to phantom lending, and after almost 9 months they still do not fix problem with 2FA authentication skip). Poloniex was awesome exchange but this is kinda reason why they lost half of the volume to Bittrex. Just from my point of view, it took god damm 4 hours to withdrawn lisk to around few minutes on the withrawn on bittrex. And I'm not even talking about that Bitcoin Cash scam and BTC withdrawn, where they basically refusing to credit BCH to pedning bitcoin withrawal and also refuse to proccess BTC withrawal. They are currently under US investigation for some possibly un-legal operations with DAO.
