mkmloom comparing BTC lost through exchange failures and insolvencies against the Coldcard incident, claiming Coldcard accounted for 0.081% of the amount and arguing for diversification and self-custody. A community reframing of the incident's scale; the figures and comparison method are the poster's own, not verified here. Captured through the site's public GraphQL API: the rendered pages crash the capture tab, and the API answers POST from this host. The query fixes the captured surface to the item's title, text and two levels of comments, each with author and absolute timestamp.

Every check is recorded, including checks that found no text change. A detected edit is therefore bounded between two checks. The publisher's exact save time is not observable from this record. Last checked .

Gox \\~850,000 BTC (hack, 2014)\nCelsius \\~235,000 BTC (insolvency, 2022)\n3AC \\~175,000 BTC (fund collapse, 2022)\nGenesis \\~150,000 BTC (insolvency, 2023)\nBitfinex \\~119,756 BTC (hack, 2016)\nFTX \\~100,000 BTC (fraud, 2022)\nBlockFi \\~77,000 BTC (insolvency, 2022)\nQuadriga \\~76,000 BTC (CEO's death, 2019)\nVoyager \\~65,000 BTC (insolvency, 2022)\n\nColdcard \\~1,500 BTC\n\nColdcard accounted for 0.081% of the amount lost by exchanges.\nFor every bitcoin lost due to this bug, custodians lost over 1,200 BTC.\n\nThe error is avoidable: diversify, use multisig, create your own entropy, and never put your BTC on a CEX.
