Question: volatility of bitcoin vs stocks

A common criticism I've seen of bitcoin in the past is that it's manipulated by bad actors, pumping and dumping. I don't buy it, and so I'm wondering if there's a good explanation for why bitcoin is able to rise and fall so rapidly compared to other assets? I'm trying to understand why similar phenomena isn't seen in the stock market - well-performing stocks don't move the way bitcoin moves. The only comparison coming to mind was GameStop a few years ago (or a couple other meme stocks around that time), but this isn't typical of hot stocks.

Are there rules in place (e.g. stock market open and close) that prevent traditional stocks from building the momentum that bitcoin has during it's highs and lows? Or is there simply that much more volume of bitcoin being traded compared to other assets?
