Mt. Gox was a Tokyo-based largest cryptocurrency exchange of the world, that operated between 2010 and 2014. It was responsible for more than 70% of Bitcoin transactions at its peak.
In 2014, Mt. Gox was hacked, and thousands of Bitcoins were stolen; the company filed for bankruptcy shortly thereafter.
In late 2021, creditors and the Tokyo District Court reached an agreement on the Mt. Gox rehabilitation plan, closing a seven-and-a-half-year legal battle.
