maybe that's not the only reason john mcafee to stop promoting ico because it's risking his reputation
What reputation? His reputation as a scammer and con-artist?
More likely he's just made enough money for now - he was charging $105,000 per tweet. No doubt he'll be back with another shady as hell scheme in a few months when the money runs out again.
Most likely this would be the case. We dont know on whats behind on that mask on such reasoning of that dumb ass but rest assured he do already make some serious amounts on crypto-field. I didnt know that he do charge up too much with just promoting or per tweet. Mcafee is famous but int the field of traditional assets and stocks thats why he do made impact when he chill out things. For now he must rest because no one do really believe in him anymore and SEC was just a pure alibi.
