Cryptocurrency may be a threat to America’s national security and more regulation is needed in the space now, Commodities Futures Trading Commission Chair Rostin Behnam said today. 

Behnam said cryptocurrency was “potentially a threat to national security” when Senator Roger Wayne Marshall (R-KS), who described the space as a “nuclear bomb going off,” asked about digital assets being used by criminals. 

Behnam told lawmakers that his agency needs to be able to have the power to write rules and oversee crypto trading—including stopping exchanges from having affiliated entities that trade with customers on the platform.
