IMHO his blogs are perfect. He gives twice a day a BTC video update that is mostly used for his TA teachings. Together with his tutorials it is a perfect for everyone who got intrested in learning something about TA.
The rest of his blogs are several alt calls which is perfect for me since I simply don't have the time to go and check the entire market on regular basis (I'm working full time and my dream is to get enaugh profit to quit my job and invest all my time into my own little startup).
I couldn't be more grateful that I've come across @haejin, to me his blogs are priceless and I solely registered on steemit to support him (along with many others).
