[ZachXBT Warns of JuCoin Withdrawal Issues and Reserve Transparency Concerns] According to a post by ZachXBT, the East Asian exchange JuCoin has been reported by multiple users over the past week for abnormal withdrawal issues. The proof of reserves disclosed on X claims a total reserve of approximately $511 million, but the majority consists of USDC and USDT issued on its proprietary chain, JuChain, raising doubts about the actual backing. JuCoin's ownership structure is opaque, and the publicly disclosed team is suspected not to be the actual controlling party. JuCoin attributes the delays to upgrades and restructuring and has undergone multiple name changes in the past. Additionally, it was revealed that JuDAO suffered a $225,000 loss in April 2026 due to a smart contract vulnerability and a $20 million loss in September 2025 when 77 million POL tokens were locked due to an agent contract deployment error.
