Mt. Gox was once the world's largest Bitcoin exchange, but in 2014, it collapsed in a scandal that shook the cryptocurrency world. Millions of Bitcoins belonging to customers of the exchange were lost or stolen, and the exchange declared bankruptcy.

In 2019, long after the collapse of Mt. Gox, an old wallet containing 16,000 Bitcoins (worth tens of millions of dollars at the time) was discovered. This wallet had been overlooked during the initial bankruptcy proceedings. It was found on an old-format wallet.dat file that was used by the exchange, and it raised questions about how such a significant amount of Bitcoin could go unnoticed for years.

The bankruptcy proceedings and the recovery of this forgotten wallet continued for some time, with discussions about how to distribute the recovered funds to the victims of the Mt. Gox collapse. It serves as a reminder of the challenges and complexities involved in resolving cryptocurrency-related legal cases and the impact of a single overlooked wallet.
