ZachXBT, a prominent researcher in the cryptocurrency space, has sounded the alarm about JuCoin, a cryptocurrency exchange based in East Asia. This matters to everyone, as issues with exchanges can directly affect users’ investments and financial security.

Withdrawals and Transparency Issues

ZachXBT recently reported that many users faced difficulties withdrawing their funds from JuCoin. This has led to serious concerns about the exchange’s financial health and transparency. When users can’t access their money, trust in the platform begins to erode. People need to understand that withdrawal problems can indicate deeper issues within an exchange.

In March 2025, ZachXBT first warned about JuCoin, pointing out potential risks despite the exchange’s high-profile sponsorship at the Token2049 event in Singapore. Surprisingly, recent analysis suggests that JuCoin’s reported reserves of $511 million may not be accurate. The exchange’s reserve assets mainly consist of USDC and USDT tokens issued on its blockchain, JuChain, but the details behind these assets remain unclear. This lack of clarity raises questions about the actual financial backing of the exchange.

Ownership and Control Concerns

Another worrying aspect is the opacity of JuCoin’s ownership structure. ZachXBT indicated that the publicly disclosed team might not have true control over the exchange. This is a red flag, as some offshore exchanges often operate in a similar manner, keeping their real managers hidden from investors. Transparency in ownership is essential for any business, especially in finance, where trust is paramount.

JuCoin has attributed the delays in withdrawals to ongoing platform upgrades and restructuring efforts. However, the exchange has undergone multiple rebranding efforts in the past, operating under names like Jubi, JuCoin, and Joy Universe/Ju. Frequent rebranding can signal instability, making users more anxious about the exchange’s true nature.

Past Security Incidents and Reputation

Tied to JuCoin is JuDAO, which has faced its share of troubles. Reports state that in April 2026, $225,000 was lost due to a smart contract vulnerability. Additionally, in September 2025, about $20 million worth of assets became inaccessible due to a misconfigured proxy contract. These incidents further damage the reputation of the JuCoin ecosystem, raising alarms for potential investors.

ZachXBT highlighted another concerning detail: approximately $5 million related to the Bybit attack in 2025—allegedly associated with North Korean cyber activities—was reportedly channeled through JuCoin. This connection is troubling, especially considering JuCoin’s recent announcement to provide financial backing to Bybit amounting to 1,000 BTC.

The Need for Transparency

In assessing centralized cryptocurrency exchanges, transparency in ownership and regulatory compliance are crucial. ZachXBT criticized JuCoin for falling short in both these areas, making it difficult for users to feel secure about their investments. The exchange has yet to deliver a detailed response addressing these serious concerns, leaving many questions unanswered.

Investment in cryptocurrencies carries inherent risks, and exchange issues can multiply those risks greatly. It’s essential for users to remain informed and cautious. Keeping an eye on alerts from trusted researchers like ZachXBT can help keep potential investors safer.

What this means for you

For everyday users, the story of JuCoin is a lesson on the importance of checking the security and transparency of any exchange you choose to use. Transparency issues can often occur in contracts you might review, such as employment agreements.
