CZ: Although the Binance hack set a record in USD terms, its impact is far smaller than that of Mt. Gox

CZ posted a response to the discussion that the Binance hack had limited impact on Bitcoin's price, stating that the $6.3 billion stolen this time is the largest in USD terms, but not in terms of Bitcoin quantity. Mt. Gox lost approximately 650,000 BTC back then, accounting for more than 5% of Bitcoin's total supply, and its impact was greater.CZ pointed out that assessing the impact of a hack also requires considering the number of affected users and the proportion of their assets damaged. In the Mt. Gox and FTX incidents, the affected users and the scale of their assets were nearly fully covered, whereas in Binance's case this time, the affected party was only the platform itself, user assets were unaffected, and the platform will bear all losses. CZ acknowledged that this incident remains a major blow to the crypto industry, to Binance, and to himself, but emphasized that Binance can survive the crisis, and that protecting users is the most important thing.

Former CEO of Mt.Gox Questions Ledger's Misleading Marketing: Security Claims Contradict Technical Documentation

Former Mt. Gox CEO Mark Karpelès (@MagicalTux) posted that Ledger Support (@Ledger_Support) stated on August 20 that the Secure Element chip can detect physical tampering; if extra hardware intercepts signals, the device will refuse to execute unsigned code or fail the Genuine Check. Karpelès pointed out that Ledger's own technical documentation explicitly states: if the original Secure Element is intact, the Genuine Check cannot detect unauthorized physical hardware modifications such as spy implants. The two statements contradict each other. He also noted that recent reports show over $90 million in assets were stolen precisely through this method of "extra hardware intercepting signals." Furthermore, in a March 2026 Ledger Academy article, Ledger had already published photos of spy implants installed inside multiple Ledger devices, including mass-produced complex PCBs, indicating they were long aware of this threat. Karpelès believes this conduct constitutes misleading promotion and cited that French law has specific regulations regarding misleading advertising.
