Cryptocurrency marketplace NiceHash said Wednesday that hackers stole the contents of its virtual wallet, making off with digital currency reportedly worth more $60 million. The breach was announced the same day Bitcoin rose 18.2 percent to cross the $13,000- and then $14,000-per-coin trading milestones for the first time.

NiceHash, a marketplace for cloud-based mining of cryptocurrencies, made its announcement following an hours-long outage attributed to "maintenance" and reports from NiceHash users that their wallets had been emptied. NiceHash paused operations for 24 hours to determine how many bitcoins were stolen and how. But a Coindesk report suggests the wallet contained 4,736 bitcoins, worth about $66 million at current prices.
