CMC is not always accurate regarding the current price. The BitUSD price in $ is calculated using various other ratios like BTS/BTC, BTC/USD etc. and CMC doesn't bother to make sure that these other price ratios have the same timestamp.
This means that when the price of BTS rises quickly externally and BitUSD internally has low volume or doesn't trade at all CMC will show an unrealistically high BitUSD/$ price.
