[South Korea FSS to Investigate Abnormal API Cryptocurrency Trading Activities] The South Korean Financial Supervisory Service (FSS) stated that API-based cryptocurrency trading accounts for approximately 30% of market transaction volume. Some traders use automated tools to inflate trading volume and manipulate prices, including repeatedly submitting small orders to create a false sense of activity and using high-priced limit orders to drive up prices. The FSS will investigate accounts suspected of engaging in abnormal API trading and remind investors to be cautious of assets with sudden spikes in price and trading volume. South Korea had previously required exchanges to verify asset balances every five minutes and strengthen anti-fraud rules, but some regulatory measures remain constrained by legal frameworks.
