Market sentiment can be a wildly powerful force in crypto. Look back at summer—$ETH was hovering around $1,600, and the narrative was brutal: it's finished, no use, dump it, no hope whatsoever. Fast forward and it's touching $4,800. Suddenly everyone's kicking themselves for not accumulating when the price was down. That whiplash between "this asset is dead" and "I wish I'd loaded up" pretty much sums up how sentiment swings can reshape entire market cycles.
