One thing I notice about these crypto snipers and other high-profile crypto traders who buy tokens before launch is that most of the time they have some marketing arrangements with the project owners, who sometimes might give them a hint on information about the project, and they can decide to invest a large amount in it before launch and take some of the marketing strategies into their own hands.
I feel and see things this way because, after this massive profit and after their selling in a few weeks to months or so, we will always see the market dropping and correcting itself back to normal, which is why those who bought through the hype of the crypto snipers will be recording losses.
