According to Wu Blockchain, on-chain investigator ZachXBT has questioned FinCEN’s estimate of approximately $16 billion in illicit transactions involving MEXC, suggesting the figure may be inflated and calling for supporting data and comparisons with other exchanges. At the same time, he acknowledged that MEXC's past anti-money laundering (AML) and KYC practices were relatively lax, while raising questions about potential U.S. regulatory overreach and the swift actions taken by some offshore exchanges to restrict MEXC-related transfers. The above represents the views of ZachXBT.
