He is getting 100k$ per tweet where he promote some shitcoin,dont really know how much is he asking for icos where he does more then 1 tweet.Dont really think that after all the stuff he did last months anyone takes him serious anymore...
He is hyping some cryptos and because of his influence many people can lose. Its like a bounty campaigns also,but he is popular already and he makes money about it. I remember that many ICO before that has a tag name " endorsed by John McAfee". But really, he has influence.
