Ledger CEO Rebukes Mt. Gox Ex-CEO Over Hardware Security Warning

The exchange is less a technical debate than a credibility contest between two figures carrying very different histories in crypto security. Gauthier's demand for "known facts" over speculation lands awkwardly given his own company's role as a security vendor defending its record, so the substance of Karpelès's hardware-implant warning risks getting lost in the personal back-and-forth. For self-custody users, the open question is whether either side actually produces verifiable detail about the risk rather than trading barbs. How this dispute develops — and whether it stays rhetorical or turns evidentiary — is worth watching.
