Hargreaves Lansdown, the UK's largest investment platform, has advised investors to avoid including digital assets in their portfolios, citing Bitcoin's lack of intrinsic value. The company plans to conduct further risk assessments before potentially allowing access to crypto exchange-traded notes (ETNs). This caution comes as the UK's Financial Conduct Authority (FCA) lifted a 2021 ban on retail access to crypto ETNs, while still labeling them as high-risk investments. Recent FCA data indicates that 12% of UK adults now own cryptocurrency, a significant increase from 4% in 2021.
