My take is whatever McAfee says, you'd be a fool to take trading advice from him, he's a nutjob, has quite a shady reputation, and was shilling ICO's for a fee. He can give you a solid advice about Bitcoin today, and then give you a horrible advice tomorrow, because someone had paid him to. No self-respecting trader would get their advice from someone like McAfee, or any other self-proclaimed expert. People who do are generally newbies who are easily manipulated.
