US bitcoin ETFs see $4.6 billion in volume in first day of trading

US-listed bitcoin exchange-traded funds (ETFs) saw $4.6 billion worth of shares trade hands as of Thursday afternoon, according to LSEG data, as investors jumped into the landmark products approved by the US securities regulator on Wednesday.

The products mark a watershed moment for the cryptocurrency industry that will test whether digital assets – still viewed by many professionals as risky – can gain broader acceptance as an investment.
