Yes in quantum all occurs at the same time, only difference being we perceive a linear experience. This understanding can make it easy to wrap your head around the fact a price can go up before the event that should cause the spike in price. There have been studies to show we can predict events moments beforehand, so without 'knowing' why peoples interest in something, lets say BTC may increase before they necessarily have rationale to explain why.
So the herd might start buying in droves then 'the event' comes which we dont know what it is so far, then we collect our massive profits thanks to Haejin! lol
