Because people are as much of an idiot as McAfee himself is. If you buy into the rubbish he is granting shine through his Twitter account, you're a straight sheeple without any self respect and thinking capabilities. If McAfee can make you buy into whatever rubbish, then pretty much anyone with a large following can do. Greed has taken over nearly everything crypto stands, which is pretty destructing in my opinion.

Also, I thought that he was a billionaire, but it seems that he isn't. He's a fairly common multi millionaire with a net worth well below $10 million according to various sources. This pretty much explains why he's accepting payments for Twitter promotion. I was wondering why a billionaire would ever do that, but it's clear now. He's not a billionaire.
