Jerry is a machine, and he understands how to manipulate systems better than anyone I have ever seen, almost better than Tai and Gary Vee as well.
He knows that on here, the name of the game is to talk and write nothing but positive things about Steem and Steemit, or any cryptocurrencies for that matter, because he knows that's the thing to do.
Never underestimate this guy. He got kicked off of Udemy because he understood the system so well, that the others on the platform collectively came together to remove him. He would canibalize others classes, and rock it better than them.
The man never sleeps. He finds new things, and he dominates them. The man truly is a master marketer, but never forget... that he is dangerous. If you try to do the things he is telling you to do, you will most likely fail, because you don't have the connections he does.
The other things he preaches are very cookie cutteresque, so those won't hurt you, but I don't think pouring money into any of the new "ideas" he is conjuring up, which are most likely not his ideas, he's just a spokesman, I advise that you do it very cautiously.
