ChainCatcher news, the case of "virtual asset T-Coin pyramid scheme" with 30,000 victims in South Korea has recently been prosecuted by the Eastern District Prosecutors' Office in Seoul. The individuals involved, including Choi and Lee, promised high returns under the guise of "investing in T-Coin, AI automatic trading" from 2017 to 2019, collecting a total of 3.9251 billion won.Since the case received complaints in September 2020, it has gone through a complex back-and-forth between the police and prosecutors, until the newly appointed prosecutor Lee Sang-won took the initiative to intervene, re-examine the case, and gather complainants for investigation, ultimately transferring the case to court within six months. The former prosecutor commented that this case highlights the phenomenon of evasion and delays in investigations between the police and prosecutors.
