There are two explanations, one of which is greed, or that the user was trying to get more profits through referral links or promoting the site. In any case, I know many friends who stop thinking once they hear that there are free profits that will be distributed without effort, or that there are A site that makes you deposit an amount of money and get a fixed interest daily with the possibility of withdrawing the amount.
When a person watches Youtube cryptocurrency about trading bots, they make it sound like it's true. I didn't know a person could hijack a Youtuber.
I hope that it will be a lesson for him and that he will not be one of the site's promotion team who have been scammed.
