<ul data-eligibleForWebStory="true">Polyhedra Network's ZKJ token has plummeted 91% due to abnormal on-chain activity and liquidity issues.Binance attributes the token crash to whale exits and a resulting liquidation cascade.Concerns are raised about liquidity risks, tokenomics, and the impact of large holders in DeFi.The ZKJ token dropped from $2.00 to $0.2676 in less than 24 hours, wiping out nearly $500 million in market cap.The crash began with abnormal transactions on Polyhedra's ZKJ/KOGE pair, leading to an 83% price drop.Large KOGE withdrawals triggered a liquidity crisis, intensifying the sell-off and price decline.Whale activity, including massive withdrawals and margin calls, exacerbated the sharp decline.Binance has revised its Alpha Points rules for ZKJ and KOGE to minimize systemic risks.An upcoming token unlock of 15.5 million ZKJ tokens on June 19 adds to bearish sentiment.This unlock, valued at $10 million, could flood the market, potentially causing another steep drop.
