Harvard economist Kenneth Rogoff argues that cryptocurrency is gradually eroding the global dominance of the US dollar. In a recent interview, he asserted that digital currencies are gaining traction in unformal markets where the dollar once held sway. This shift, according to Rogoff, could significantly impact both the U.S. economy and international financial power. He points to Bitcoin’s increasing use as a safe haven asset during periods of market volatility or economic pressure as a driving factor behind this trend. 20-25 trillion USD in crypto markets, largely fueled by digital currencies, are now being used as an alternative to traditional cash in these informal economies.
