Of course not. Those guys just like to put on a show, and they are quite good at it. Crypto is a very speculative market, and most people don't use their head when they invest, so they want to be reassured by people with a high profile like McAfee, and they just bet blindly on their projections. Since a lot of people do that, it actually works in some times.

With this I'm not saying I don't believe in bitcoin, because I do. It could perfectly reach those values, but there is no reason to say that. Bitcoin needs to evolve, and even with good development it still needs good adoption, and for that people need to accept it and understand it. I think this will be the hardest part to be honest.
