Bitcoin tumble below 78k as Binance scare sparks selloff
Bitcoin fell more than 4% to about $77,995 on Friday as the Binance security scare dragged ether and BNB lower and forced traders to unwind leveraged longs.

Risk appetite in crypto cracked again on Friday morning Asia time. The Bitcoin tumble below 78k left the largest token more than 4% lower at $77,994.96, extending the break that started when prices lost the $80,000 handle.
What happened
Ether dropped 4.84% to $2,247.45 and Binance Coin slumped 7.68% to $694.45, CNBC reported, while Hyperliquid's HYPE token bucked the tape with a 9.7% jump to $89.08 on separate ICE news. Circle and Tether had already frozen a combined $2.54 billion in stablecoins tied to the suspected Binance breach late Thursday.
Binance still framed the episode as a potential security issue under investigation, even as founder Changpeng Zhao said it appeared to be a hack and the exchange pledged to cover losses. Arkham's map of nearly $6 billion across 55 wallets kept traders focused on how much might still be moving.
The move sits on top of a fragile October for bitcoin, which had already tested the low-$80,000s on Fed jitters and weekend war headlines before this scare. Forced deleveraging typically amplifies the first leg of a mega-exchange shock, and Standard Chartered flagged more near-term pain in market commentary cited by CoinDesk.
Liquidation cascades usually hit hardest in the first 12 to 24 hours after an exchange scare, when basis trades unwind and market makers widen spreads. That pattern helps explain why BNB underperformed spot bitcoin even before any confirmed on-chain burn of exchange reserves.
Derivatives positioning amplifies every spot break in this range. When bitcoin loses a round number that options dealers and prediction markets have been marking, gamma and liquidation engines can force the same direction for hours even without fresh fundamental news. That is the mechanical layer beneath Friday's Binance headline.
Why it matters
The Bitcoin tumble below 78k matters because $78,000 is now the line traders are watching into month-end, after the market already failed to hold $80,000. It also lands alongside the bitcoin Fed jitters that thinned Strategy's cushion and the bitcoin round-trip liquidations that showed how fast longs get wiped when spot gaps lower.
Stablecoin freezes limit how quickly stolen funds can be cashed out, but they do not restore the leverage that just got cleaned out. Until Binance reopenings look clean, spot bids stay defensive.
Options and prediction-market strikes clustered around $78,000 and $80,000 now dominate the weekend tape. A bounce that fails at $80,000 would keep the October low narrative intact.
What's next
Friday's close and Saturday's Asia session will show whether $78,000 becomes a base or a waystation. Price action detail is in CNBC's bitcoin market wrap.
Stablecoin freezes and Binance's own recovery work are the two variables that can either shorten or extend the risk-off window into November.
On-chain and exchange balance data will be watched as closely as the spot candle. If large wallets keep distributing into strength, any bounce toward $80,000 may fail for the same leverage reasons that amplified the break below $78,000.
