Looks like a bug with Atomic Trade. If you click on the price of BTCD at coinmarketcap you will see a list of the exchanges and the price. Atomic Trade is listed with a price of $11 for BTCD while the others are all ~$1.10. That is why the average is so much higher.
Well atomic last trade api shows 0.01880000 BTC per BTCD
Someone bought some coins on that price
