AFAIK, Crypto ETFs are baskets of shares of selected crypto companies. I think a cryptocurrency ETF exists already, but it includes ETH and other shitcoins. The ETFs under SEC scrutiny would include btc only. What's more, some of them are designed for settlement in kind, not in cash (that is, bitcoin - not USD). The importance or usefulness of such a financial instrument is debatable, but it can't be dismissed as "nothing new".

Where's the novelty? Everyone would be able to buy (paper) btc through their stock market broker, without having an account at an exchange. Besides, if the settlement is really in kind, the ETF issuer would have to hold/buy/sell matching amounts of the underlying asset (btc) or bear the risk when the ETF holder asks for payment. That is, if fuckery can be ruled out. Which is a big IF.
