Poloniex Exchange:
WoW On May 2, 2017, the following will be delisted: BBR, BITS, C2, CURE, HZ,
IOC, MYR, NOBL, NSR, QBK, QORA, QTL, RBY, SDC, UNITY, VOX, XMG
It seems like a manipulation. Delist right before the events. Maybe someone wants to get low.
I hope Poloniex will change their mind about UNITY delisting.
