The six largest cryptocurrencies, including the flagship bitcoin, have all sunk in the last 24 hours, according to data from Markets Insider, following a major cyberattack against a Japanese cryptocurrency exchange last week which resulted in the loss of $400 million.

Bitcoin, which still makes up 33% of the entire digital currency market cap, was down 4.6% to $11,297 at the time of writing. Ethereum and Ripple’s XRP token, the second and third largest cryptocurrencies, were down 4.6% and 6.3%, respectively, at $1,184 and $1.30 per token.

Smaller coins with market caps of less than $1 billion had also taken a hit.
