Top Examples of Crypto Thefts in History

1. Mt. Gox (2014): Once handling over 70% of all Bitcoin transactions worldwide, Mt. Gox was a significant player in the early days of Bitcoin. 
However, the platform was hacked in 2014, resulting in a loss of around 850,000 Bitcoins, then worth around $460 million.

2. Coincheck (2018): The Tokyo-based exchange suffered one of the biggest crypto heists when hackers stole NEM tokens worth around $534 million. The attack exploited a weakness in Coincheck's security system, as the exchange stored its assets in a hot wallet instead of a much more secure cold wallet.
