Is the fact that there are a bitcoin ETF such a milestone?

There is an inverse-Cramer ETF: SJIM (The Inverse Cramer ETF does the opposite of his suggestions, short-selling his buy recommendations and buying his sell recommendations in the expectation that the stocks will do the contrary) and an Meme Stock ETF (MEME). There’s even an ETF that just invest in companies that treat people with disabilities as well (RODI). Does this make bitcoin closer to being the global currency? The introduction of bitcoin ETF was supposed to lead to big institutional investors buying in. This is not happening. Anyway, why would big institutional investors need an ETF to buy into bitcoin?
