Fraudulent activities by a cryptocurrency trading platform across multiple countries, affecting user asset security. The platform attracted investors through false advertising of high returns, while actually running a Ponzi scheme. Investigation revealed that the platform has defrauded approximately $50 million worth of cryptocurrency from over 10,000 users globally in the past 6 months. The platform operators concealed fund flows through complex cross-chain transfers, but PANDA community members tracked the main fund flows using blockchain analysis tools. The whistleblower provided detailed transaction records, false promotional materials, and communication records with platform operators as evidence.

Evidence is sufficient, fraud has been confirmed, and the highest level of reward is recommended for the whistleblower. The review team has submitted relevant evidence to law enforcement agencies in multiple countries and assisted in freezing some of the stolen funds.
