It is not their fault! Since they have been hearing about some ETF approval all over the place, they just assumed it would be a saving grace for the market. Whether it is a saving grace or not, I guess time will tell. However, it is always normal for newbies to be enthusiastic about gains and will always want to come up with their own theory of how they expect prices to be at certain point in time.
I'm not blaming them, I saying that they are believing mostly that its the only way for the price increase of bitcoin. I've been there as well and I know what they feel but they have to understand that its not the only thing that we can hope for some heads up in the market. Decision will be coming out next year's Q1 so that's still a long way to go and I won't be shocked if they will delay it again.
