The hefty bitcoin heist is the latest in a series of digital thefts that have hit the financial marketplace. However, despite this, Bitcoin’s value is still rising in the market, according to Kitco. The value reached $7,000 per coin Monday.

Zhao Changpeng, Binance’s CEO said the theft was “well-orchestrated” and “the hackers had the patience to wait.” The company said it will cover users’ lost funds with its Secure Asset Fund for Users (SAFU), which is emergency insurance.

In a tweet about the incident Zhao said Binance would remain transparent.
