JuCoin is facing fresh scrutiny after on-chain investigator ZachXBT flagged user complaints about withdrawal delays and questioned the exchange’s reserve claims. Summary ZachXBT said JuCoin users reported withdrawal delays over the past week, raising exchange risk concerns. JuCoin’s reported reserves face questions over USDC and USDT issued on its own JuChain. JuCoin blamed delays on upgrades and restructuring while critics pointed to past JuDAO incidents. Wu Blockchain reported that several users had raised withdrawal issues over the past week. ZachXBT also questioned JuCoin’s reported $511 million reserves, saying much of the value appeared tied to USDC and USDT issued on JuCoin’s own JuChain.

The complaints arrived during a period of added concern around centralized exchange reserves and user access to funds. JuCoin attributed the delays to platform upgrades and restructuring, according to Wu Blockchain. The exchange’s explanation did not fully end concerns because users were also asking about reserve quality. “Multiple users have reported withdrawal issues on JuCoin over the past week,” Wu Blockchain said, citing ZachXBT’s comments. The issue remains developing. There has been no public proof that JuCoin is insolvent, but withdrawal delays often draw fast attention because users depend on exchanges to process funds on demand. Reserve claims face JuChain stablecoin questions The larger concern centers on JuCoin’s reported $511 million reserve figure. ZachXBT questioned whether the reserves were backed by clear third-party assets. A separate PANews-linked report said JuCoin claimed a 123.81% reserve ratio. It also said assets listed as USDC and USDT on JuChain were project-issued tokens, not clearly linked to Circle or Tether-issued stablecoins. That claim matters because a token named USDC or USDT on a private or smaller chain may not carry the same backing as official stablecoins unless verified by the issuer or a supported bridge. The report also said the reserve address held nearly all of those tokens, with only a small number of holders. That raised more questions about whether the reserve figure reflected real liquid assets. Past JuDAO incidents add pressure Wu Blockchain also cited ZachXBT’s note that JuDAO suffered a $20 million incident in 2025 and a $225,000 exploit in April 2026. Those past events have added pressure to the current withdrawal debate. Users often look at past security events when judging whether an exchange or linked ecosystem can manage stress. JuCoin has said the current delays relate to upgrades and restructuring. That explanation may be valid, but users still need clear timelines and proof that withdrawals can resume normally. In exchange crises, communication matters. Unclear updates can increase fear even before any full technical or financial review is complete. Exchange reserves remain a market concern The JuCoin case comes as traders remain sensitive to exchange reserve claims. Crypto.news previously reported heavy withdrawal pressure after the Bybit hack, showing how fast users move funds during stress. Reserve reports can help build trust, but only when users can verify the assets, issuers, chains, and wallet controls. Self-issued assets may need more explanation than widely traded mainnet assets. Moreover, JuCoin faces two separate questions. Users want withdrawals processed, and the market wants clearer proof behind the $511 million reserve claim.
