Bitcoin plummets after hackers steal $37 million from South Korean cryptocurrency exchange Coinrail
Bitcoin has once again demonstrated its volatility, dropping in value by 10 percent following news of an attack and theft from the South Korean exchange Coinrail.
Coinrail has confirmed that it suffered a "cyber intrusion" and while it did not specify the value of the coins stolen, local news outlet Yonhap News estimated it to be $37.28 million based on a loss of about 30 percent of the coins traded on the exchange.

The exchange said that 70 percent of its coin and token reserves had been secured and two thirds of what had been stolen had since been frozen or recalled. The remaining one third is currently being investigated. News of the hack caused Bitcoin to drop to $6,752 -- a huge drop from the all-time high of $20,000 just six months ago.
Coinrail took to Twitter to confirm the attack:

At the moment, the Coinrail website is offline, and a message explains that the site is in maintenance mode because of what is described as a "hacking attempt". The message says (translation from Korean via Google Translate):
