Cryptocurrency exchange JuCoin has recently drawn market attention due to withdrawal processing delays and reserve disclosure issues. Multiple users have reported experiencing delays when withdrawing funds from the platform over the past week. On-chain investigator ZachXBT subsequently raised questions, focusing on the exchange's disclosed reserve size and asset composition.
Withdrawal delays raise user concerns
According to user feedback compiled by Wu Blockchain, some accounts have experienced delays in receiving their withdrawals after requesting them. JuCoin responded that the issue is related to platform upgrades and internal restructuring, and stated that the delays are temporary.
However, this explanation did not completely quell external doubts. For users, the core issue is not just the technical adjustments themselves, but when funds can be withdrawn normally again, and whether the platform can clearly explain the current processing progress.
The composition of the $511 million in reserves is under scrutiny.
In addition to withdrawal issues, ZachXBT also raised questions about JuCoin's disclosed reserves of approximately $511 million. The controversy mainly focuses on assets labeled as USDC and USDT, which operate on JuCoin's own network, JuChain.
There are concerns that these assets may not be official stablecoins issued by Circle or Tether, but rather tokens with the same name issued by the project team on its own blockchain. If this is true, these assets may differ significantly from the official versions in terms of credit backing, liquidity, and redemption capabilities.
The concentration of reserve wallets has also attracted attention.
The report also mentioned that the relevant reserve assets may be highly concentrated in a single wallet, while the number of holders across the entire network is limited. This means that even if the on-paper figures are high, it is still difficult for outsiders to determine whether these assets have sufficient liquidity or can be independently verified.
Currently, publicly available information does not indicate that JuCoin is insolvent. However, with withdrawal delays not yet fully resolved and reserve details lacking sufficient explanation, market skepticism regarding its transparency is growing.
Going forward, the focus will be on: the time it takes for withdrawals to resume, the true issuers of the stablecoin assets in the reserves, and whether these reserves can provide clearer on-chain proofs.
