I would like to nominate @jerrybanfield. This guy is very knowledgeable about crypto currencies, produces regular informative content, he got into bitcoin before most, bought into dash when it was just a few dollars and now he is fully behind Steem, which he also knows a great deal about.

Jerry is the reason I am on Steemit after viewing a youtube video of his. He uses ALL the money he earns from his steem posts, which is thousands of dollars a day, to further promote the Steemit playform. He does this with Facebook adverts etc. So if you would like to see the steemit platform grow and go mainstreem then upvoting and spreading the word about this guy helps us all. His posts are well worth the many upvotes they receive, if you like to learn, follow this guy @jerrybanfield
