If you want some real people that understand investing and trading then let me know. Plenty of people on youtube that run paid groups that are making their clients money even in the most bearish markets. @haejin only looks good because of a bull market. I can make all the post and prediction he does and make it so easy to understand you could make better calls than he can.
It's funny that if you look at some of his calls they have a small spike in volume about 12 - 24 hours before he makes his posts. Is he giving the whale that upvotes him insider information before he posts, or does he see that small spike in volume and that's when he makes his call.
I've tracked a few of his calls for the past couple of weeks and he seems to be about 50/50 on his predictions on something going up or down.
Some good people to follow are boxmining (here on steemit and youtube), cryptodaily (here on steemit and on youtube), crypto investor (i think here on steemit and on youtube), data dash, cryptogrinders, high alititude investing, etc. You'll notice the people who are truly looking to help others to invest will sometimes provide TA's on what to expect, but back it up with why, information on the coin, and usually tell you on what bottoms to buy. Not that the coin is about to rocket to the moon and get on before it's too late. Those people are just trying to shill the bags they bought at the hi.
