Maybe the whales do it simultaneously because when you know the group that has whale members and give one order to buy or sell coins on the market then they will be able to move the price of coins on the market, a system like this has been used by many whales who always combining all its strengths into one to move the market.
If they work together to move and influence prices, of course it is very possible and everyone will be affected by what they do. They are clearly big investors and are able to do whatever they want, but sometimes what they do cannot be done simultaneously and inconsistently so that trading can run normally and is not affected by what they do.
It's certainly not easy for whales to equate perceptions because they also have desires that may not be the same.
I don't think the whale will think about that, whales will usually start price movements starting from news about cryptocurrencies in the big media, after that whales will try to raise or make prices fall depending on the news published.
I'm not interested in discussing "How" or "Who" is moving prices, I'm only interested in "When" they will do it

The crypto space is full of many kinds of news that make us confused.
So forget the noise and focus on the strategy we have set based on the research we have done.
And don't forget to prepare plans A, B, and C for the "exit plan" when the situation is not as we expected
