Hanhan, who claimed to be Kong Jie's assistant, added QQ on QQ. He first recommended stocks, and then induced investment in Bitcoin accounts, followed by copying operations. He followed up with the self-proclaimed Jiang at around 8:00 pm on June 7, 2022, Beijing time. Kaijing’s online class bought a lot at 29,300 points, and then there was a malicious slippage of more than 6,000 points to more than 23,000 points within 1 minute, and then pulled back to 29,300 points instantly, causing the account to be liquidated. After the assistant applied for the account to be cleared, the account was deposited with USD 1,326 on June 15, 2022. After submitting the withdrawal application, the withdrawal was refused.
