There is a story, as on the eve of the Great Depression Rockefeller was cleaning his shoes from a street cleaner. And the cleaner asked him if it was worth selling shares or waiting a little longer? After that, Rockefeller called his stock exchange broker with the order to sell all the securities at once: "If there is already a shoe cleaner on the stock exchange, then there's nothing for me to do!".
Even if this story is fake, do you think it can happen with bitcoin?
