On August 2nd the Hong Kong-based Bitcoin exchange Bitfinex was compromised for roughly $70 million worth of Bitcoin. According to sources, the attacker managed to drain the exchange through its multi-signature security gaining 120,000 BTC from the breach. Now the exchange is trying to reach out to the responsible party in an attempt to get its customers Bitcoin returned.

The question is if bitfinex itself was the mastermind in the hacking. First and foremost bitfinex is a large company and has the capability of spending millions to investigate using very highly skilled programmers. It is just an opinion but I do hope bitfinex is guilt free and will be successful taking back the coins. Whether it inside job or done by outside hacker the bitcoin is impossible to retrieve.
