Bitcoin's rally is turning out to be bad news for Coinbase, the crypto trading app that has just confirmed some of its customers are seeing a zero balance across their Coinbase accounts. Likely, the app's crash has to do with the recent demand for Bitcoin, the popular cryptocurrency that has surged to $60,000 -- close to its all-time high last seen in 2021. The price of Bitcoin climbed in the wake of U.S. bitcoin spot ETFs, driving a 42% price rally this month.
