According to online reports, ZachXBT issued an article pointing out that although Circle continues to emphasize compliance, the USDC stablecoin has actually become the main infrastructure for payments by North Korean IT workers. He said Circle was currently taking no steps to detect or freeze such suspicious activity, and said he could point to recent transactions that had reached eight figures. ZachXBT believes that this serious issue has not attracted enough attention in the current "crime super cycle."
