If you look at all the coins on Bittrex you see they are all in the red. That is because Bitcoin and ETH prices jumped today. so most people pulled out to ride the BTC wave knowing alt's would decline at the same time, then they could buy back in to MCO at a low rate and ride that pump. If you still have MCO, Don't lose sleep over the decline, in-fact this is a good time to buy more because the big pump is coming real soon.
