Will non crypto investors actually GAF about the BTC ETF?

As a long term casual holder of a number of cryptos I am very interested in how the ETFs will affect the crypto ecosystem but a famous quote of "when your cab driver is giving investment advice it's time to sell" keeps popping into my head.

Everyman and his dog is now a crypto expert and I see posts and articles giving million pound estimates and so on.

As per the title are people interested in the market or is it just going to be the new thing until the next new thing comes along.

If investors aren't rushing to buy in the next year or so will it hurt crypto more than help?

Apologies for the word soup title
