‘I trusted you to do better’ – Ex Mt. Gox CEO slams Ledger for inadequate response

Former Mt. Gox CEO Mark Karpelès criticized Ledger’s response to hardware implant warnings, questioning whether earlier communication could have prevented losses. Karpelès said Ledger received reports of spy hardware implants as early as December 2025. He accused the firm of responding inadequately. According to him, Ledger’s only response was a blog post about a compromise in March 2026. For him, Ledger could have done more to prevent the CryptoBillis incident, where users lost over $90M. I do know a better communication on this at the time could have saved 90+ million USD in losses.
