Who cares anymore about what McAffee says? The guy is delusional or paid for stating absurd things...
OK, he created an antivirus program, but what did he do in crypto to care about his opinions? He shilled altcoins or ICOs at some point and he created a
BTC faucet which never paid (I tested it personally; after delaying the payments they also stopped answering emails) which was also removed from Google Play.
So why care so much about his statements? All that I find interesting about him is what he will say at the end of the year, when he is supposed to eat his own dick

He is no longer on the bitcoin bandwagon so no eating dick on TV

.
Seriously, as you have pointed out he is delusional to begin with, I can' recall how John started his career in crypto though, he just suddenly burst into the scene thru his twitter paid altcoin shilling and then his outlandish 1$ million predictions. So we wait for the next personality who can match or even outgunned him as far as shilling cryptos.
