Due the nature of Bitcoin being a new asset class, it will be even worse and people go to the extremes (FOMO or panic selling), as years go by and assuming nothing wrong happens with the fundamental technology, these swings will be smaller in % long term as price grows.
Seriously, people react as if some 10 year-long trend has reversed, but in reality this $20,000k price was just a short-lived fluctuation and people are just salty that they missed the opportunity to sell at 3x times higher price than today, so they are looking for scapegoats. And with all the predictions it's clear that so many Bitcoiners still threat Bitcoin as get rich quick scheme, they expect to get big returns in a few weeks or a few months, very few people are treating Bitcoin as a long-term investment for years or decades.
