For retail crypto investors, a Treasury designation against an exchange carries serious practical consequences — including the potential loss of access to funds held on the platform and the risk of secondary liability for continued use. Industry observers note that the MEXC action could accelerate a consolidation trend pushing users toward regulated, U.S.-compliant exchanges.
