Mainly FUD from different sources. ICO banning by South Korea is now old news that is not the cause of this probably. But let me guess is this something new in crypto? Its not because its a monthly dump that occurs and new people cash out on it.

This is a good time for people to get into the market. People wont be able to buy after this when the pump occurs by whales. There may be some news coming up soon why this happened but I am sure the market will recover in a few days whatever be the reason.
