What is gox?

Gox was a Bitcoin exchange based in Tokyo, Japan that was founded in 2010 by Jed McCaleb. It quickly became one of the largest Bitcoin exchanges in the world, handling around 70% of all Bitcoin transactions at its peak. However, in 2014, the exchange was hacked and lost around 850,000 Bitcoins, which at the time was worth approximately $450 million. The hack led to the bankruptcy and eventual closure of the exchange, resulting in significant losses for its customers. The incident remains one of the largest cryptocurrency exchange hacks in history.
