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.
The only thing they need most of the time is actually the ability to read emotions on the charts, but believe me, they know much about technical analysis as well, and they make use of that to their advantage, knowing the response that would be gotten at some points that would likely favor them.
However the thing about a whole lot of them is that they have nothing much to worry about as long as the market remains purely speculative, which is what makes it very easy for them, in the aspect of the market getting even more matured and getting used in real life, I guess it is something that would really be of great help to the space, and whales will not really be having more of an influenced.
