Steem dollars are way overpriced right now on Poloniex. Great arbitrage opportunity. With the current BTC price, if you can manage to transfer your SBD's over to Poloniex quickly enough, you stand to make 64.5% profit.
671.48 USD/BTC*0.00245 BTC/SBD=1.645 USD/SBD
Happy Poloniex day.
See you on the moon.
