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 totally agree with your thoughts. Many people still use techniques to analyze price charts but I think it's useless. This is a psychological battle between investors and whales. If you catch up on it, you will definitely be rich. Otherwise, you will die. That's the rule and we can not do anything else! 
which we know this had been very volatile anytime that will cause such failure on most analysis out there which is being used.The thing we can talk
about Whales is that they can make decisions depending on what they are trying to do and since they have the capability its either they would
line up with technicals or completely derailing into their own.
