As traditional institutions pour money into bitcoin, the cryptocurrency's latest meteoric rally to a record high may have more legs than in 2021, experts say. The world's largest cryptocurrency, notorious for its volatility, touched $69,202 on Tuesday, driven by excitement over new U.S. spot bitcoin exchange-traded funds (ETFs) and expectations the Federal Reserve will begin cutting U.S. interest rates this year. Just months after retail exuberance helped drive bitcoin to its previous record in November 2021 the cryptocurrency crashed, taking half the crypto industry with it.
