TA guys are such a bunch of jobless bullshitters. Every prediction is a fail. Every video is just there to make real money from Google Adsense ...
If you dont want them to earn money then stop using youtube. TA works but dont depend on that always because the market are volatile and any news it can affect the price. TA is not just about how you analyze the market, its also good for you to have patience and to invest on a well mannered decision.
