According to reports by Wu, on-chain detective ZachXBT pointed out in a post on platform X that the stablecoin USDC issued by Circle is widely used for receiving payments by North Korean IT practitioners. He discovered that the recent transaction volume related to this has reached tens of millions of dollars. ZachXBT criticized Circle for claiming to be 'compliant' while failing to take freezing or monitoring measures, sarcastically stating, 'This is a criminal super cycle, and no one cares.'
