Mr. Beast is one of the most influential figures on YouTube, I think he has the largest channel on YouTube and gets millions of views daily and makes imaginary profits from these views, so I do not expect that he deliberately deceived his followers.
I mean, he gets much more profits through YouTube than he will get by promoting pump and dump coins, if he loses the trust of his followers, his channel will definitely end and he will lose, so I do not expect that he deliberately deceived his followers.
I do not know if the accusations are true, but the mistake is primarily on the followers who are influenced by the words of celebrities and do not conduct their own research before investing in any coin. And secondarily, on these celebrities who betray the trust of their followers.
