I disagree with you on this because I believe that technical analysis is actually important or if not that at least following the news and I also think that big investors also care about this when looking to buy coins because otherwise they might just as well throw that money away - which is unlikely.
Thing is Technical Analysis is not everyone's cup of tea. It a totally different branch and it needs intellectual and educated people to actually understand and apply it. Not that every next door get-rich-quick wannabe trader would be able to profit from it. What happens is that due to peer pressure some wannabes like the OP, enter the market hoping to make some profit by their "friend" who gave them some tips of TA. Fact is most people are like that wont use their own brains to decide their trading methods.
End of the day the "friend" goes to a profit because they sold when the person in question bought and thats what they were actually doing altogether. Trying to pump so they could dump.
