That's a good news. From what I understand, Steem deposits and withdrawals will now be available on Poloniex. People who have their Steem or Steem Dollars stuck on Poloniex will surely benefit.

Listing on more exchanges is the most exciting part imo. Currently, Steem's major chunk of volume outside Steemit is on Bittrex and Poloniex. It is listed on Livecoin, HitBTC and Tidex as well but the volumes are negligible and there isn't much trade activity on them.

More exchanges means more investment in Steem and it will lead to rise in value. Merely the news of Steem listing on more exchanges, especially the Chinese ones, can surge the value to Steem to another level. Binance is one such exchange that is going to be big I think.

Steem On!
