Bitwise CEO Hunter Horsley highlighted that Bitcoin spot ETFs launched in 2024 with a market capitalization of approximately $2 trillion, closely mirroring the $2.5 trillion gold market valuation when gold ETFs debuted in 2004. Horsley used this comparison to demonstrate that both asset classes possessed substantial market depth prior to the introduction of regulated exchange-traded products. The U.S. spot Bitcoin ETF approval in 2024 established a regulated allocation channel for traditional investors, paralleling the trajectory of gold ETFs which became essential tools for institutional and retail participation in the early 2000s. This historical parallel suggests Bitcoin's current market maturity aligns with gold's status at the inception of its own ETF ecosystem.
