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 think that the only thing that is in our favor is our luck. If we are lucky then we will gain profits. The indicators are there so that we can analyse the market.
There are great tools to know about how bitcoin has behaved in the past but the indicators cannot guarantee of assured gains as predictions in crypto are not right most of the times.
Though indicators can still be used to limit the losses and risks of loosing money.
