If they want to add PKB they can but I won't be pushing PKB to other exchanges just yet because it has been slow but steady trading since launch.

C-Cex added it and all the volume is still on Yobit, looking at the daily volume at C-Cex it will soon become at risk of being removed due to low volume, which was one of the reasons I didn't contact them to begin with.

I get the feeling miners are dumping around the 300-400 mark because they do not care for the coin only small profit, Once POW ends (next 24hours/3-4000 blocks!) volume should start picking up as newly minted coins will reduce to around 250k PKB a year and current figures show over 1million of the premine will be burned.
