When hackers penetrated a secure authentication system at a bitcoin exchange called Bitfinex earlier this month, they stole about $70 million worth of the virtual currency.
And when hackers got past the first layer they discovered the entire joint was wide open and just aching to be emptied. If their customers knew that's how it was going to be then I don't think there would've been anything left to hack.
That's if it was an outside hack of course. If we knew what was a genuine hack and what was an inside job we may be rather surprised at the stats.
