I haven't follow McAfee but are you saying that he no longer accepts payment to shill for some ICO or tokens? How come? I guess if this so called group of developers will come up with a DEX that is revolutionary then perhaps John can bounce back and get his "reputation" back. But until then, people are going to remember him for making outlandish claims and predictions and a paid shiller.
He moved on to accept payments to shill products and put his name on them. LOL
He started with that shit hardware wallet which got hacked in 3 days, then the trading platform which charged a $50 (IIRC) to do nothing and now he created this DEX where he controls the private-keys.
None of these projects are made by him. All of them pay him to be the "face" of the marketing. I wouldn't touch anything "McAfee approved" with a ten foot pole.
