South Korea’s Financial Supervisory Service (FSS) issued a warning to investors trading on decentralized exchanges, citing a sharp increase in memecoin scams that use fabricated positive news to attract buyers before a rug pull.
The warning, reported by Yonhap News, describes a pattern of tokens promoted heavily on social media shortly before listing, followed by a rapid liquidity drain that leaves the token worthless.
FSS Warns Investors to Watch Fake Hype and Token Concentration
The regulator said many of the crypto scams involve tokens created with little or no legitimate development activity, where anonymous teams fabricate news articles or endorsements to create a false sense of legitimacy. Once enough buyers enter, developers drain the liquidity pool, causing the token’s price to collapse almost immediately.
The FSS identified concentrated token ownership among a small number of wallets as a primary red flag, since such concentration raises the risk of a coordinated sell-off.
The agency recommended investors use blockchain explorers to review transaction histories and watch for large transfers to exchanges shortly after a token’s listing, in addition to checking a project’s whitepaper, team background and roadmap before investing.
Warning Follows South Korea’s First DEX Rug Pull Prosecution
The alert comes weeks after Seoul prosecutors filed the country’s first criminal case targeting a decentralized exchange rug pull. The Seoul Southern District Prosecutors’ Office charged five people on May 27 over a Solana-based memecoin called CATFI, in what prosecutors described as South Korea’s first DEX rug-pull case.
Prosecutors said the lead suspect, identified by the surname Park, operated under the online persona “Eth Father” and promoted CATFI as an independent third-party project.
Investigators said the group used social media campaigns to drive the token’s price up more than 1,000-fold within about 26 hours before draining liquidity, causing roughly 900 million won, or about $600,000, in losses for 256 investors.
The case was prosecuted under South Korea’s Virtual Asset User Protection Act, which took effect in July 2024 and had previously been applied mainly to centralized exchanges. The FSS said DEXs lack the consumer protections typical of centralized platforms, placing the responsibility for due diligence on individual investors.
