He is amazing! @jerrybanfield is one of the most famous people in online advertisement and education. In last three years, I have done more than a dozen online courses on a variety of topics, including blogging, from a variety of sources like Udemy and Coursea. This is the reason I know Jerry Banfield from the pre-Steemit era. I frequently checked his ads and also was a follower on his Facebook page.

He has done a tremendous job at promoting Steem(it). He doesn't seem to stop. He also invested handsome amounts into Steem in May-June 2017. I remember seeing 88,000+ SP in his wallet when I joined. To be fair, he's done a great job at multiplying his own investment, as well as ours. Kudos!
