Binance Hack Rumor Sinks Crypto Market, Wipes Out Longs

All news is rigorously fact-checked and reviewed by leading blockchain experts and seasoned industry insiders.

This is a developing story and will be updated as more information becomes available.

• Claims of a Binance wallet drain spread on social media, but no hack has been confirmed.
• Long positions took almost all of the forced liquidations, most of them within a single hour.
• BNB fell harder than any other top-ten coin, pointing to fear about the exchange itself.
• Hyperliquid stood out as the one large asset where short sellers carried the losses.

The crypto market extended its slide late on Thursday, October 29, after on-chain monitors flagged roughly $2.77 billion leaving Binance wallets across five blockchains and posts on X started describing the movement as a possible Binance hack, which would make it one of the largest exchange breaches on record. Binance has not confirmed a breach, and the transfers could still prove to be an internal reshuffle of exchange funds. The timing, however, collided with a derivatives market packed with leveraged long bets, and CoinGlass liquidation data showed $620.41 million in forced closures within a single hour, out of $951.23 million for the full day. Bitcoin traded at $78,929 at the time of writing, while total crypto market capitalization stood at $2.67 trillion, down 1.69%.

A Tornado-Funded Wallet Raised the Alarm

The claim gaining traction says a Binance wallet was emptied into a newly created externally owned account, a standard address controlled by a private key with no smart contract behind it, and that the gas for the contract call came from funds routed through Tornado Cash. That second detail is what turned a large transfer into a hack rumor. Exchanges usually pay fees for internal moves from their own labeled hot wallets, whereas attackers often seed fresh addresses through a mixer so the source of the gas money cannot be traced back to them.

The receiving wallet’s own Etherscan history complicates that reading. Its first funding came from an address labeled Binance 14, and its largest deposit, 28,005.6 ETH, arrived minutes later from another labeled exchange wallet, Binance 16. That trail fits an exchange moving reserves into a new custody address, although it does not rule out a compromised internal key, since anyone with access to Binance’s signing systems could also send funds from labeled wallets.

No blockchain security firm has publicly linked the outflows to a theft so far, and Binance has previously disputed outflow tallies built on third-party wallet labels, arguing that aggregators do not verify which addresses actually belong to the exchange. Anyone who wants to check balances directly can compare the exchange’s own proof of reserves page with the independent DeFiLlama exchange transparency dashboard, which tracks holdings address by address.

October has left traders primed to react before the facts arrive. The Drift Protocol exploit drained $285 million on Solana, Bitget lost up to $387.5 million from its hot and warm wallets in late September, and India’s CoinDCX admitted a $16 million loss days after first denying a fresh breach. With that record in mind, many traders chose to cut exposure first and wait for confirmation later.

Why One Hour Did Most of the Damage

A liquidation happens when a leveraged position loses enough value that the trader’s posted margin no longer covers it, at which point the exchange closes the position at market price. For a long opened at 20x leverage, a drop of about 5% is enough. Every forced sale pushes the price slightly lower and brings the next cluster of liquidation levels into range, so on thin order books the process can run through several layers in a matter of minutes.

Thursday’s numbers fit that pattern closely. Longs accounted for $599.62 million of the $620.41 million liquidated in the hour, roughly 97%, while the 24-hour tally showed $802.14 million in longs against $149.10 million in shorts. Positioning was fragile before the rumor surfaced: two Federal Reserve policymakers had backed a quarter-point rate increase at this week’s meeting, and Bitcoin had already slipped below $80,000 during the Asian session as technology stocks sold off, which left many dip buyers with liquidation prices sitting just under the market.

What makes the late-evening drop stand out is that Bitcoin had held around $80,000 through the US session while technology stocks sold off, even though it has tended to trade in step with the Nasdaq for most of the past few years. The Nasdaq Composite closed 1.38% lower after Alphabet’s results reopened the debate over AI spending, with the Google parent losing about 13% in its steepest one-day fall on record after reporting negative free cash flow of $9.07 billion and keeping its full-year capital expenditure forecast at $195 billion to $205 billion. Intel added to the pressure after the bell, falling close to 20% in after-hours trading on a weaker revenue forecast, so crypto lost that relative calm just as the selling in big tech names deepened.

BNB Fell Hardest, HYPE Squeezed Shorts

BNB gives the clearest read on how the market priced the rumor. The token dropped 5.99% in an hour and 6.95% over the day, the worst result among the ten largest cryptocurrencies, while Bitcoin lost 2.64% across the same 24 hours. BNB’s value is closely tied to activity on Binance and BNB Chain, so traders tend to sell it first when doubts emerge about the exchange, and its relative weakness says more about the rumor’s impact than the broad market decline does.

Hyperliquid’s HYPE moved the other way and ranks among the day’s biggest gainers, up 13.73% over 24 hours and 19.02% over seven days. The token dipped alongside the rest of the market when the Binance claims surfaced, but buyers quickly recovered part of that drop, and it was the only large asset on the liquidation map where shorts absorbed most of the losses, with $25.55 million wiped out. The rally began well before the Binance claims appeared, so reading it as a flight from centralized exchanges would be a stretch, although traders will watch whether volume on the on-chain derivatives venue keeps climbing while the questions around Binance stay open.

What Would Settle the Hack Question

The most direct answer has to come from Binance itself. A statement from co-CEOs Richard Teng or Yi He describing the transfers as a planned wallet migration would likely ease much of the pressure on BNB, while silence through the Asian morning would keep the rumor alive. Withdrawal processing matters just as much, because an exchange that has actually lost funds typically pauses outflows on the affected networks.

On the trading side, the size of the flush has already removed part of the leverage that made it so violent. Funding rates, the periodic payments exchanged between long and short traders on perpetual futures, will show whether buyers start rebuilding positions at lower prices, and a move back above $80,000 would return Bitcoin to the range it held before the Fed meeting.

For scale, the October 10, 2025 crash liquidated about $19 billion across exchanges after new US tariffs and Chinese rare-earth export controls hit risk assets, which puts Thursday’s daily total at roughly one-twentieth of that event. Binance later said it saw no large-scale withdrawals even during that episode, and that is the standard traders will hold the exchange to if the latest transfers turn out to be routine.
