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.
If you are trusting a project due the person promoting it the you are living in a fool's paradise looking for fool's gold. The person making the investment is you and thus you are yourself responsible for your investment and not anybody else.
Crypto has always been a cult operation. It becoming mainstream only means trouble - trouble like this. And if someone falls for these paid shills then its their fault for drinking koolaid secreted by those FUDstars.
