Twenty two year-old hacker Jimmy Zhong said he never meant to become a criminal billionaire. But that’s what happened in 2012 after he found a way to steal bitcoin from the Silk Road – a dark web exchange then known for some of the most unsavory trade on the internet – drugs, guns and porn. Over the next decade, the coins Zhong stole rocketed in value, ultimately reaching an eye-watering $3.36 billion.
