If you are checking coinmarketcap now, you might notice that some coins are in the red.
For whatever reason coinmarketcap.com decided to exclude the prices for several coins from Korean exchanges because they were a lot higher than on most exchanges.
I think this decision is somewhat questionable when we are talking about global currencies.
The last time I checked the Korean prices Bitcoin was 3.000$ higher than on other exchanges, Ripple was around 5$ per coin and Bitcoin Cash about 1.000$ more than on other exchanges.

Update: Yep, nevermind, everything is dipping.
