I'm following Haejin and did want to do the analysis, which you have posted above. So thx for it!
Don't know if it is really honest to pin point him on one coin only, but I do have a feeling that the scores for other coins will be at the same level.
He only looks at the chart and forgets that emotion has more impact that TA on the coins. Certainly at this moment, with all the FUD and rumors.
People are just following him on Steem to be the first to up-vote to generate some money I guess.
A TA could give you an indication what could happen but should be adjusted with the emotions at that moment. It should be one of the steps in predicting a price movement but not the only step.
