Younger high-net-worth investors are allocating far more of their portfolios to alternative assets than older peers, reinforcing Grayscale's view that the category could become a long-term growth driver for crypto. Bank of America survey data cited by Grayscale show investors aged 21 to 43 keep 53% of their portfolios outside traditional stocks and bonds, compared with 26% for those older than 44. Grayscale head of research Zach Pandl said the global alternatives market has expanded nearly sevenfold since the 2008 financial crisis, with private equity, private credit, hedge funds, real assets and crypto assets taking a growing share of portfolios. The report said easier access through new financial products, trading platforms, regulated bitcoin ETF and ETP products, and institutional-grade market infrastructure may help sustain that shift as more than $100 trillion in wealth moves to younger generations over the coming years.
