I am still thinking if what will happen in Bitcoin once Bitcoin ETF will be approved, it will become just like Gold ETF when it was started? Because if yes, for sure a lot of people will do FOMO and it will just drive the price of Bitcoin to a crazy high, most people will use gold as the basis for Bitcoin being approved on ETF.
ETF is new thing and more serious because, it's institution, more money is already involved and more people will be exposed to Bitcoin via Bitcoin ETF.
