A company in Seoul, B, has been issuing unlisted coins for several years to raise investment and recently held investment briefings targeting the elderly, touting high returns and recommending investments in A coin and D coin. In the past, it issued D coin and listed it on Gopacks, but its trading support was terminated due to operating without a VASP license, and the price plummeted by 98%. Currently, B company is recommending investment by exchanging D coin for a new token, but many investors are hesitant to file lawsuits due to their past experiences of damage. In domestic cryptocurrency exchanges, dozens of coins have their trading support terminated every year, and these cases show that scams through unlisted coins are increasing. Experts argue that a regulatory clarification should be made to create an environment where legal tokens can be distinguished from fraudulent projects.
