Poloniex trys to manipulate the market by freezing wallets. Best thing you can do is leaving Poloniex and trade on a DEX. Just look at he BTC/BTS price to see how this works.

This coin is already trading on so many exchanges I also will do agree while there is option to switch another exchange which is better than Polo. Polo will remain controversial due to that kind of stupid action and in past they manipulate so many markets even these projects were dead.
