Mt. Gox Hack

One of the world's largest exchanges, Mt. Gox, declared bankruptcy in 2014 after being hacked, while losing most of its assets. At the time of bankruptcy, the exchange held 200k $BTC.

Mt. Gox was a bitcoin exchange based in Shibuya, Tokyo, Japan. Launched in 2010, it processed more than 70% of all Bitcoin (BTC) transactions worldwide by the beginning of 2014.

At the beginning of 2014, Mt Gox, a bitcoin exchange based in Japan, was the largest bitcoin exchange in the world, handling over 70% of all bitcoin transactions worldwide. By the end of February of that year, it was bankrupt.

Anyone who was using Mt. Gox lost access to their assets, and it has been a cautionary tale for crypto investors. While the assets weren’t all lost, anything that was left has been frozen for years.

The victim of a massive hack, Mt. Gox lost about 740,000 bitcoins (6% of all bitcoin in existence at the time), valued at the equivalent of €473 million at the time and over $3 billion at October 2017 prices. An additional $27 million was missing from the company’s bank accounts.
