Woofun AI reports that Jeremy Grantham, co-founder of asset management firm GMO, stated Bitcoin will not collapse overnight but will fade into irrelevance over years or decades. In an interview with CNBC, Grantham described Bitcoin as a speculative asset with no intrinsic value or practical use, citing its extreme price volatility and lack of utility in everyday transactions compared to gold. He noted that while gold maintained an upward trend during recent economic expansions, Bitcoin's value was cut in half "for no particular reason." Grantham argued that Bitcoin's primary function appears to be facilitating anonymous cross-border money transfers for criminals. Despite increased institutional adoption and the launch of spot ETFs in the US, Bitcoin remains highly sensitive to macroeconomic factors and regulatory news. Central banks continue to hold significant gold reserves, whereas Bitcoin remains largely absent from institutional balance sheets.
