I think that is because bitcoin is about the people, the hodlers. If the hodlers keep falling sick and not able to be active to buy and sell which would increase trade volume etc, that could be a logical reason IMO .
Hodlers sit on their chair or sofa staring at the screen all day to see if Bitcoin finally surpassed that $100,000 level. They're hardly buying even though many of them are loudly presenting themselves as "dip buyers". It's just the same nonsense as we have always had. Very retarded bull narrative. I'm confident that most of these "hodlers" don't hold many coins to begin with.
Most of the people wishing for $100,000 only do that because they know that they need such insane valuations to see their holdings grow in value much enough. You won't be getting rich with a few tenths of a whole coin, neither with a whole coin which many can't afford nowadays.
In the end, it doesn't matter how many times we go through these corrections, people even if they have been here for a couple of years never get used to them. They always catch them by surprise.
