According to @KookCapitalLLC, an X post on Sep 8, 2025 claims a 'biggest hack in history' hit during a euphoric up-move, with no protocol, amount, or confirmations disclosed, highlighting acute headline risk for BTC, ETH and altcoins (source: @KookCapitalLLC on X, Sep 8, 2025). For immediate risk control, traders can cut leverage, trim thin-liquidity altcoin exposure, and wait for verified statements from the affected project, centralized exchanges, and reputable security monitors before repositioning (sources: Binance Futures Risk Warning; SlowMist security incident monitoring; PeckShield Alerts). Near term, some desks hedge net exposure via BTC or ETH perpetuals or rotate to stablecoins while spreads widen and volatility resets, then re-enter once exploit scope is confirmed (sources: CME Group Bitcoin/Ether futures hedging primers; Binance Research derivatives market guidance).
