BlockBeats News, May 19th, according to Bloomberg, U.S. Democratic Senator Elizabeth Warren is questioning a financial regulatory decision that allows cryptocurrency companies to access the banking system, stating that some of these companies "seem to be unfit."

The Democratic senator from Massachusetts wrote to the head of the Office of the Comptroller of the Currency (OCC), Jonathan Gould, stating that the regulatory agency has approved national trust bank charters for at least nine cryptocurrency companies, and these companies "seem to be far beyond the narrow business scope allowed by law," which "clearly violates the National Bank Act."
