The $70 million Coldcard loss is significant, but pales in comparison to the largest crypto hacks ever recorded, which have collectively cost billions.

The top 3

  1. Bybit Hack: $1.5 Billion (2025): The largest crypto heist to date occurred in February 2025, when hackers exploited a private key leak in Bybit's hot wallet system, stealing approximately $1.5 billion in Ethereum.
  2. KelpDAO Hack: $292 Million (2026): In April 2026, attackers compromised a third-party system used by KelpDAO, allowing them to fake collateral deposits and release approximately $292 million in unbacked crypto assets.
  3. Drift Trade Hack: $285 Million (2026): The Drift Trade platform suffered a $285 million loss in April 2026 after attackers used social engineering to gain privileged access, create a fake token, and manipulate its value for collateral.
