Yeah Ju formerly JuCoin is obviously bad but can someone succinctly explain why Tether "is just fine, nothing to see over here."
We don't need no stinkin' audits just check our attestations, the Tether founders say.
An exchange that claims half a BILLION in reserves just stopped letting people withdraw. The reserves are mostly a stablecoin it printed itself. The team behind it is hidden.
The exchange is Ju, formerly JuCoin. Users have reported being unable to withdraw funds for the past week. Ju says the delays are due to upgrades and a restructuring tied to a publicly listed company.
The numbers don't hold up. Ju self-reports $511 MILLION in total reserves. An on-chain analysis found that the vast majority of that is USDC and USDT that Ju issued itself on JuChain, its own blockchain, with no clear backing behind it.
In other words, the exchange is counting tokens it printed as proof it can cover customer funds.
ZachXBT first warned about Ju in March 2025, when it appeared as a Platinum sponsor of Token2049 Singapore. He flagged the red flags then. They've only multiplied since.
The history is the tell. Ju has rebranded repeatedly. JuBi became JuCoin became Joy Universe became Ju. Its earlier versions were accused of listing fake tokens, manipulating trading depth, and blocking withdrawals.
One predecessor reportedly cost over 100,000 investors their funds.
The ownership is hidden. The public team doesn't seem to actually control the exchange. The real operators stay out of sight, the company is registered in a place with almost no oversight and the names attached to it keep changing.
That's how fraudulent offshore exchanges are usually built.
JuDAO was also exploited for $225,000 in April. It lost $20 MILLION in September 2025 to a botched contract deployment that left 77 million POL stuck.
At least $5 MILLION tied to the Bybit North Korea exploit was moved through Ju, just weeks after Ju publicly offered Bybit up to 1,000 BTC in support.
The test for any centralized exchange is simple. Is the ownership transparent and is it registered somewhere serious. Ju fails both.
If you have funds on Ju, the withdrawal delays are not the risk. They are the warning.
