The assessment is based on strong, consistent, and direct evidence from multiple high-authority sources. Two primary reports from major South Korean news agencies (with authority scores of 0.90 and 0.85) explicitly state that financial authorities are considering and positively considering a 'payment suspension' (지급정지) system. The purpose of this mechanism is clearly articulated: to freeze accounts and prevent the withdrawal of profits from suspected cryptocurrency price manipulation. This core claim is further supported by contextual evidence from other credible financial news outlets, which confirm that key regulators like the Financial Services Commission (FSC) and the Financial Intelligence Unit (FIU) are actively focused on cracking down on market manipulation ('시세조종'). While several sources discuss broader crypto regulations without mentioning this specific mechanism, none of them contradict the claim. The highest authority source, the National Assembly's legislative records system, would be the definitive source for a formally proposed bill; its lack of mention in the provided summaries is consistent with the reporting that the mechanism is currently in the 'consideration' phase, rather than being formally legislated. The low-authority source also directly echoes the claim, which, while not evidence in itself, aligns with the information from credible reports. The convergence of direct reporting from highly credible sources, strong supporting context, and a lack of conflicting evidence makes the statement highly likely to be true.
