I don't think that price is ever possible to achieve in near future as bitcoin will never go that low now and in fact it will keep on increasing from now so its good not to waste your time hoping to buy at that price as that day will now never come and if you want to buy then buy it now as every day is a good price to buy bitcoins if you can hold it longer.
We don't know
how much of a bubble the ETF hype is. It very well could crash below $500 again and then bounce back slowly in case ETF is declined
I think it can be claimed with certainty
Namely, that there is no big bubble or hype tied to ETF approval expectations. It's basically because no one really expects the ETF to be approved, so no fertile soil for such expectations, to begin with. The price may decline somewhat at the moment when rejection is announced, but that would be no more than a knee-jerk reaction to a negative news. For example, major Chinese exchanges had been expected to allow Bitcoin withdrawals lately but they didn't and this affected the price. And what do we see? The price went down less than 150 dollars (a little over 10%, usual thing with Bitcoin) and now it is going up again
