In 2018, crypto boss Zhang, through Yao Qian from the People's Bank of China's Digital Currency Research Institute, reached out to a certain virtual currency exchange to help successfully list a token on the exchange and raise 20,000 ETH. Later, Zhang gave Yao Qian 2,000 ETH as a thank-you gift, worth over 60 million yuan at one point. The corruption and shady dealings behind the crypto world were exposed by CCTV. Guess which exchange? Which project?
