The Financial Supervisory Service (FSS) of South Korea announced that API-based trading now represents about 30% of the cryptocurrency market's buy-and-sell turnover. The FSS expressed concerns over traders utilizing automated tools to manipulate market prices, including tactics such as executing repeated small trades and spoofed orders. To address these issues, the FSS plans to initiate investigations into accounts exhibiting excessive or abnormal trading patterns. This move aligns with South Korea's ongoing efforts to enhance regulation in the crypto sector, particularly in light of recent fraud incidents. The FSS outlined various manipulation methods, including artificially inflating prices through higher-priced limit orders and simulating trading activity to lure retail investors. As regulatory scrutiny increases, the FSS cautioned investors to be wary of high-frequency trading codes available online and to avoid assets with sudden price spikes without clear justification. These enforcement actions come amid a backdrop of legal challenges, as seen in a recent court ruling that highlighted gaps in the regulatory framework governing cryptocurrency exchanges.
