Former employees of three failed exchanges reveal insider withdrawal privileges, high-yield Ponzi mechanics, and platform-token manipulation schemes targeting lower-tier markets.

A former employee who worked at WebSea, JuCoin and CoinUP disclosed that these three exchanges, which have since failed, employed overlapping tactics to retain user capital. The mechanisms included platform-token appreciation strategies, discounted token sales, high-yield products, copy-trading features, and tiered agent recruitment networks. During a 2024 crisis at WebSea, insiders including employees retained withdrawal access while ordinary users faced restrictions. JuCoin deployed mining products and multi-level agent structures to acquire users in lower-tier markets, while some CoinUP leadership and agents were compelled to purchase the CPX platform token before it collapsed in price.
The former employee observed that withdrawal privileges were stratified by user tier. At JuCoin, withdrawals exceeding prior deposits faced reduced approval odds, and gains were sometimes deducted. Ordinary users encountered withdrawal locks that did not apply equally to employees, agents, and other insiders. The account suggests that smaller exchanges may rely increasingly on platform-token mechanics, high-yield offerings, and geographic user acquisition targeting during downturns, patterns that obscure the structural risks embedded in "principal protection" promises and discounted token models.
What remains unspecified: the scale of user losses, timeline of each failure, whether regulatory action has been initiated, and whether other exchanges employ similar tiered-access or Ponzi-adjacent structures.
