Cramer, and all social/public personalities, ...it doesn't matter if you're right or wrong, full of stuff or not....you just have to be polarizing and charismatic. To entertain the, rather, brain dead, sheep zombie masses out there.
Look at the, real, successful traders in history and modern life...they are all boring, rather incredibly boring people. George Soros, Ray Dalio, Dan Zanger, Japanese trader BNF, Jesse Livermore, Steve Cohen, Nick Leeson, etc etc....
....all of these boring people would fail on social media to generate a huge following, despite their meteoric successes.
