This is a good one, and lets add to that many other influencers! Many of them are taking money for that, and they talk about what they are paid for. In McAfee case its a proven thing. I follow many of them and I read what they wrote, and in many cases its funny. I wouldn't trust them with my money.
Do a research, and make your own decision is the best thing anyone can do. Avoiding FOMO, FUD, and other stuff is hard, they are always be here, on forums, social networks, who is active cant miss that. Only thing is focusing on your choices and interests, let others do their talking and you do what needs to be done!
