John Mcafee is very well known in the online world because of mcafee antivirus and recently cryptocurrency.
Do not listen to this guy's investment advice. He takes bribes to promote certain projects. Last time I heard it was 100k usd for him to shill your coin.
This guy is a constant lier and is not to be trusted.
He already admitted that he takes money to promote projects. He has lost all credibility after he did that and it may affect his other businesses. All the scammers can succeed in getting short term profits with crypto but in the long run, they will suffer.
After this incidence, I have stopped believing the recommendations of these gurus however reputed they are.
