I think, why we need regulate digital money because after nearly a decade since its invention, Blockchain has not yet reached to its full potential. Billions of dollars of investments are made every day, but none of the great potentials come to reality, despite only serving bitcoin for its payment system and allows illegal payments to occur in the Dark Web and also because of many anonymous we need regulate digital money. Other than that why we need regulate digital money because it can create demand in Bitcoin as a digital currency.
