The whales and big investors did not need indicators both (technical and fundamentals indicators) before buying or selling Cryptocoins. This has just made me to believe that the indicators are just there for me and you to lose money and not to make money as the price will still go against you no matter how intelligent you are in technical analysis. The market seeing to make it own mind and that is to say the whales push it to any direction they decide at a particular time.
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.
