Haejin's posts are more like a tool for me but i only put money in something when i'm also happy with the fundamentals and it matches other analysts predictions. How i see it, is that haejin doesn't do it to lift all weights off your shoulders but he shares how he does TA which can be even more valuable when you have the time, energy and enthusiasm to learn it yourself. I lack all of this so i always take these with grain of salt. Even that way, just following him is very profitable and i think he is a good human being compared to many so called cocky veterans and that alone makes him unique in this scene.
