Spot trading volumes on centralised crypto exchanges rose for the fourth consecutive month in January, reaching levels not seen since June 2022, as the approval of the Bitcoin ETF reignited interest in the digital asset. According to CCData, trading volume increased by 4.45 per cent to $1.4 trillion compared to December. Bitcoin (BTC) prices spiked ahead of the ETF's approval on 10 January, but have mostly fallen since then.
