Binance founder CZ: $6.3 billion stolen is the largest in dollar terms but not in BTC terms

CZ posted on X on October 30 in response to discussions about the scale of the Binance theft and the BTC price reaction, pointing out that the roughly $6.3 billion theft is the largest by dollar amount, but not when measured by the amount of BTC; he gave the example that the Mt. Gox incident involved 650,000 BTC, accounting for more than 5% of the total BTC supply at the time, so assessing market impact cannot rely only on the dollar amount.

He further said that attention should also be paid to the number of affected users and the proportion of users' assets that were affected; according to him, in the Mt. Gox and FTX incidents, nearly all users and their assets were affected, and the more critical issue is who ultimately bears the losses and whether the platform can fully cover them, rather than leaving users to absorb the losses. CZ emphasized that this incident remains a major disaster for the industry, Binance, and himself, but that they can weather the impact, and said, "The most important thing is that we protect users."

This comparison shifts the measure of losses from nominal dollar amount to the proportion of supply, the breadth of user coverage, and the party bearing the losses, highlighting the differences in capital paths under a platform full-coverage mechanism: the stolen assets are borne by the company's reserves and the SAFU fund (the company said it has set aside more than $6.34 billion to cover them), rather than being passed on to user assets, thereby limiting the price and trust shock; the beneficiaries are user-side stability, and structurally it reflects the governance arrangement by which a centralized exchange, after scaling up, shifts hacker risk from "shared by users" to "absorbed unilaterally by the platform."

ABAB AI Insight

As the founder of Binance, CZ continued to speak out on this incident even after no longer serving in day-to-day management. His comparative framework directly echoes the 2014 Mt. Gox incident (about 650,000 BTC stolen, accounting for roughly 5%-7% of the circulating supply at the time) and the 2022 FTX collapse (where user assets were comprehensively damaged). He shifts the metric from nominal dollar amount to supply share and user coverage, continuing his earlier public stance that "user asset safety comes first."

In terms of capital path, Binance said it has set aside more than $6.34 billion of company funds to cover the losses (of which about $5 billion is already held in corresponding tokens), and together with about $3 billion in frozen assets and the SAFU fund, the losses remain mainly on the platform's balance sheet rather than in user accounts. This forms a contrast with Mt. Gox (where users bore the losses directly) and FTX (where user assets were misappropriated), with the flow of funds taking the form of "company reserves absorb → zero loss on the user side," benefiting users holding USDT/other assets, while the potential cost falls on the company's profits and shareholders' equity.

Comparable cases include the roughly $1.5 billion theft from Bybit in 2025 (also attributed to a North Korea-linked hacker), as well as the exchange industry generally strengthening SAFU-like buffer funds after multiple large-scale thefts. This incident further shows that once centralized exchanges reach hundreds of billions of dollars in assets, the ability to internalize hacking losses has become a key variable for maintaining market trust, rather than relying solely on technical defenses.

Specific judgment: the platform's commitment to full coverage limited further downside in BTC prices in the short term (no direct selling pressure from the user side), but the company must use reserves and continue buying to replenish positions, which will put pressure on Binance's own liquidity and subsequent profits; if later investigations confirm more vulnerability points, scrutiny of hot wallets and DevOps permissions across the industry will tighten further.

  1. A larger dollar amount does not mean a larger supply shock.

  2. Platform-side coverage shifts losses from users' side to the company's balance sheet.

  3. It is the breadth of user coverage, not the nominal amount, that determines the severity of the trust shock.
