ZachXBT flags JuCoin over withdrawal halts and $511M…

On-chain investigator ZachXBT has publicly flagged JuCoin after multiple users reported withdrawal issues persisting over the past week, raising fresh concerns about the exchange's solvency and reserve transparency.

Why it matters

ZachXBT's central allegation is that JuCoin's reported $511 million in reserves are largely illusory — most of the figure, he argues, consists of USDC and USDT issued on JuCoin's own JuChain network, without clear third-party backing or verifiable proof of reserves. Self-issued stablecoins counted as reserves is a red flag the industry has seen before, most catastrophically with FTX's reliance on self-minted FTT as collateral. The investigator also highlighted a troubling security track record: JuDAO suffered a $20 million incident in 2025, followed by a $225,000 exploit in April 2026. JuCoin, for its part, attributed the withdrawal delays to ongoing platform upgrades and internal restructuring — a response that has done little to calm user anxiety.

Market impact

ZachXBT's public flags have historically preceded significant user exodus and liquidity crunches at smaller exchanges. The combination of withdrawal restrictions, unverifiable reserves, and repeated security incidents puts JuCoin firmly in the high-risk category for any user holding funds on the platform. Users and counterparties should treat this as an active withdrawal-risk situation until JuCoin provides independently audited proof of reserves.
