Korea Warns Investors as Meme Coin Scams Surge on Decentralized Exchanges

South Korea’s Financial Supervisory Service (FSS) has issued a warning over a sharp rise in investment scams involving meme coins traded on decentralized exchanges (DEXs), where weak listing controls and anonymity are being exploited by fraud operators.

According to the FSS, DEX platforms allow users to trade directly without intermediaries or formal listing reviews, meaning virtually anyone can issue a token. While this lowers entry barriers, it has also enabled a wave of “rug pull” schemes, where developers attract liquidity, drive up prices through hype, and then rapidly sell their holdings, leaving investors with near-total losses.

Regulators highlighted a recent case in May in which a coordinated group allegedly manipulated a meme coin’s price before dumping holdings, causing losses of around 900 million won across 256 investors. Authorities said such schemes are increasingly coordinated through social media channels and typically occur shortly after new tokens are launched.

The FSS noted that thousands of meme coins are created daily through automated platforms, with many lacking any underlying project or code development. Despite this volume, more than half of all tokens launched last year have already ceased trading, reflecting extreme market fragility and liquidity collapse risks.

Beyond price manipulation, regulators warned that DEX trading exposes investors to technical risks such as “slippage,” where thin liquidity causes trades to execute at significantly worse prices than expected. Investors are also urged to verify contract addresses carefully, as copycat tokens are frequently deployed to impersonate legitimate projects.

The FSS further stressed that decentralized platforms offer limited recourse in cases of fraud, hacking or asset loss, as there is often no identifiable operator responsible for compensation.

Authorities advised investors to avoid approving unnecessary wallet permissions, separate trading and storage wallets, and assess liquidity depth and cross-exchange listings before engaging in meme coin trading.
