this is my review about poloniex . Poloniex website is not Beginner Friendly and no Mobile App to ease that .Security level is Okay. I sometime experienced withdrawals “awaiting approval” for prolonged periods of time, despite my account appearing to be in good standing. Though I give them good credits on their Fees because it's very Low. And also Customer Support is Bad though it's something common to lots of exchange out thereSee full review
