It is not useless but don't take this analysis to be highly reliable. Haejin made several EOS TAs last 4-5 months and they all failed big time.
Read this for fun and maybe some ideas. Use fundamentals and watch what is actually going on with certain project. No TA can replace that.
TA works mostly for shitcoins, this is why you see Haejin posting ton of them every day, basically pump and dump.
