Haha, that is also a good point, one idea I have tried to express to people for a long time since pondering trends and why things happen at all, in any sector, in anything at all is; there are always unfathomable amounts of ideas, outcomes, reasons, for anything to happen at all.
In regards to trading, I have found many people get caught in the trap of thinking a market moves in any direction as a type of hive mind almost instantaneously. Traders, Investors, Speculators and everyone in between buy and sell for all sorts of different reasons and they buy and sell at different price points. The markets are a living, breathing beast.
I think you are right, a whale might play with a few million dollars but he might not care if he loses some because it's only 2% of his wealth. People who buy at different prices will have different levels at which they are spooked, some easily, some not so. some people are willing to sell at a loss, others will never sell unless their portfolio meets their requirements for retirement, FOMOers are perhaps happy to get out at break even. The variables are incalculable. To me at least.
