You are all being played! Especially you @berniesanders
Haejin Lee (Yes, that is the full name) is a media channel front for Crypto Currency Trends, a micromanging crypro day trading site, owned my Daniel Grant, who I suspect (though I do not have enough evidence) is a Binary Option Trader from the USA.
Suspiciously, the speaker in Haejin Lee's first youtube video has an American accent, but in later videos has developed an Asian accent. Also, when taking about successful investing, they sometines refer to "We" rather than "I". Haejin Lee's 36,000 Youtube followers are directed to the @haejin Steemit site for "Live updates" from the videos.
@haejin's profile picture is of actor Seo In Guk, taken from a poster for the TV series The King's Face. Here is a link to the poster: https://www.dramafever.com/st/news/images/Kings_face_2.jpg
Also, if you follow searches for Haejin Lee across all media channels, you will quickly realise that no one person could possibly produce this volume of articles, videos , and podcast consistently every day.
Let me summarise this for anyone who has yet to catch up: @haejin is not a person, @haejin is a business. The business is running @haejin as a very efficient marketing stream and fleecing us all for as much Steem as they can rake in.
You have all been had.
It took me only an hour of searching the internet to turn up this information. Tip for the future: Do your homework.
