The number that matters most from Sunday is not the roughly $6.3 billion stolen. It is the $3.64 billion that left on the first day the doors reopened, and the roughly $78,000 bitcoin price that greeted it without blinking.
Binance processed $4.65 billion in withdrawals against $1.01 billion in deposits after reopening on November 1, leaving net outflows of approximately $3.64 billion. That net figure represented roughly 2.1% of Binance’s reported $171 billion in assets, based on its proof-of-reserves snapshot taken October 31. Put another way, despite the initial rush following the hack, Binance retained assets worth about 47 times the net amount withdrawn.
How This Stacks Up Against Past Runs
The comparison markets reach for immediately is FTX. It is worth being precise about why the analogy falls short. In November 2022, FTX saw a run that effectively depleted customer confidence in a matter of days, culminating in the exchange halting withdrawals and then filing for bankruptcy. Binance shed about 2.1% in this first window after withdrawals resumed. The mechanism was also categorically different: FTX’s crisis stemmed from internal insolvency tied to misuse of customer assets, while Binance has described this incident as an external compromise of its hot wallets.
Binance says it set aside company funds to absorb the losses before withdrawals resumed, meaning a bank run met fully backed balances. That sequencing mattered. Customers withdrawing from an exchange that has already pre-funded losses face a fundamentally different calculation than customers withdrawing from one that cannot meet redemptions at all. Binance’s most recent published update before the reopen said it had replenished about 90% of the affected assets, with the remainder concentrated in less-liquid tokens it was still sourcing, funded through SAFU, a portion of its futures insurance fund, and corporate treasury.
Founder Changpeng Zhao wrote on X that “98% choose to stay,” adding that most of the net outflows occurred within the first couple of hours after withdrawals resumed. The exchange said withdrawal volumes had declined and were stabilizing after the initial spike. That pattern, a sharp early burst followed by a rapid tapering, is exactly what a functioning exchange with intact reserves should produce.
Why Bitcoin Held Near $78,000
Bitcoin spent November 1 and into November 2 trading around the high-$70,000s. The muted response reflects something worth studying. In the immediate aftermath of the Binance hack, bitcoin dipped but did not cascade the way it did during the FTX collapse in November 2022.
Three reasons account for the difference. First, the asset backing was in place before the first withdrawal cleared. Second, the alternatives are limited, as no other exchange could absorb Binance’s volumes at short notice, which dampens the incentive to exit the ecosystem entirely. Third, spot bitcoin ETFs have given institutional holders a venue that is structurally separate from exchange custody risk, reducing the reflexive sell pressure that Binance-specific stress used to generate.
The structural separation argument cuts both ways for centralized exchange competitors. Coinbase has been quietly building revenue lines that reduce its dependence on spot trading volume, which matters when a rival exchange absorbs a stress event that could redirect institutional flow.
What to Watch Before Tomorrow
The real test is not behind us. Binance said its updated proof-of-reserves snapshot was already published, but that the full zero-knowledge proof takes roughly 40 to 50 hours to generate and is expected by Tuesday, November 3.
A full backing claim on October 31 is a statement. A checkable proof on November 3 is evidence. Once published, customers holding the specified cryptocurrencies will be able to independently verify whether Binance maintains at least 1:1 backing for their assets. If the cryptographic verification holds, the confidence picture shifts considerably for BNB, COIN, and HOOD, all of which carry direct or indirect exposure to whether centralized crypto custody emerges from this week with its credibility intact.
The Trader’s Lesson
The 2.1% outflow number is the kind of data point that looks alarming in a headline and clarifying in context. Experienced traders know to ask the denominator before reacting to the numerator. A $3.64 billion outflow against a $171 billion base, from an exchange that says it pre-funded losses before withdrawals opened, is a stress test the institution appears to have passed so far, not failed. The proof-of-reserves report expected Tuesday is when independent verification replaces self-reporting. Watch that, not the withdrawal volume from day one.
