Seeing red today is because CMC is excluding Korean markets
Without any clear communication, CoinMarketCap has excluded Korean markets. The reason for that is that prices have been about 30% pricier over there and thus giving wrong valuations on their site.
As the prices & graphs tanked, a large number of people were not aware of what is going on and dumped large amount of coins in panic trying to "cut loses", being under the false impression that their coins are crashing.
You'll most probably find your favorite coins being discounted today :)
Is that being proven?
Thanks for your reply! It's just a removal of the listing on coinmarketcap (which is most frequently used for checking coin values), nothing that will affect the korean exchange in itself if you're worried about that
