I think this is expected movement - I wrote about it here:

To add to the daily trends there has also been issues with the MetaMask system for the ICO meaning most people weren't able to contribute to the ICO today and the price is really low on the main site.

Then Yunbi is currently down for maintenance and it's the Chinese exchange where 85% of the currency is traded, so without movement there the other markets are in a bit of a free fall.
