#4 The Mt Gox Heist
Those newer to the world of Bitcoin may not remember Mt. Gox. Once the largest Bitcoin exchange in the world, Mt. Gox’s story rocked the cryptocurrency world and caused a major setback for the digital currency industry. Having been the biggest exchange for most of Bitcoin’s life, Mt. Gox filed for bankruptcy in 2014, after months of tech issues. Not only that, it was reported that at some point, 744,000 Bitcoins had been stolen from the company – without anybody even realizing. With only around 12.4 million Bitcoin in circulation, this theft accounted for almost 6% of the total amount of Bitcoin available.
