The whales and big investors did not need indicators both (technical and fundamentals indicators) before buying or selling Cryptocoins.
I don't believe this is true. Even big investors have to rely on some data before hitting that buy/sell button.
Many of them became a "whale" because they know how to analyze and they would be rekt if they would just ignore those data.
Do you have other data that could back your statement? Or this is plainly your own opinion?
