This is how rug pulls happen... you listen to someone who already have shares in the company, they tell you to copy them and buy this stock.. obvs the price jumps up with the demand and they sell their shares then tell all the "followers" to sell theirs as the price will drop. obvs the price drops and they say "I told you!" and look like they can predict the future while it's them that's actuall causing it.
Also following big whales don't help you, once they already brought the shares, the price of it has already been affected and you will be paying a higher price for the shares..
The mega rich investment portfolio is way different from us humble folks, they have investments in private companies, houses and other assets.. unless they are doing as their source of income, their public stocks portfolio is a small percentage of their total investment portfolio, they can afford to place a x million pound gamble on a public company and lose out; can you afford it?
