and I also think we need more and better dex exchanges, not necessarily from McAfee
Agreed. Competition is a good thing. More DEXs from more providers results in more choice for users and more development as they have to stay competitive with each other.
The main problem we have with DEXs at the moment is a lack of liquidity. As we see more and more centralized exchanges demanding ridiculous levels of KYC data, often without warning or notice and holding customers' coins hostage until they comply, and more and more centralized exchanges being hacked for this same data, my hope is that more and more users will finally get fed up with their nonsense and start looking to DEXs instead. The whole point of bitcoin is to not have to trust third parties with your money. Why should we be trusting third parties with our trades, when they have regularly proved to not be worthy of that trust.
Having said all that, anything with McAfee's name on it usually does more harm than good. He widely publicizes it mainly at newbies who don't know he is a scammer, and when it all goes down in flames they are the ones who lose out, not him.
