JuCoin Withdrawal Freeze: ZachXBT Questions $511M Reserves

JuCoin Withdrawal freeze concerns escalated after users reported a week of worsening withdrawal delays, with on-chain investigator ZachXBT raising doubts about the exchange’s claimed $511M reserves. JuCoin said withdrawals were slowed by “platform upgrades” and restructuring, but as of June 8 it still did not provide independent proof that funds are safely backed. ZachXBT argues JuCoin’s reserve composition is largely self-issued USDC and USDT on its proprietary chain, JuChain. That structure, he says, is hard to verify because there is no independent custodian or auditor confirming a 1:1 backing with real off-chain dollars. He also points to earlier risk signals, including a reported $20M loss in 2025, a $225K exploit in April 2026, and allegations of fund-flow links tied to an exploit involving about $5M and Bybit. For traders, the JuCoin Withdrawal freeze matters for near-term liquidity and confidence. If withdrawals remain blocked or reserves stay unverifiable, sentiment can deteriorate quickly and trigger sell pressure on tokens most actively traded on JuCoin. The key catalyst is whether JuCoin can deliver independently verifiable reserve evidence rather than repeating the “upgrade” narrative.
