This is great news, also of note is the huge uptick in XEM trading volume on this exchange.  On previous viewings of XEM volume stats in April/May I saw daily volume @ HitBTC was trending in the 10K $ range, now very recently volume has spiked to 2mil $+ daily XEM/BTC volume making it the 2nd biggest exchange for XEM behind Poloniex.
