logically whales will not act every day, so only under certain conditions whales pump and dump market. from that side, every day the market sometimes moves normally, and from that technical analysis reacts, and many are successful. but of course it's not only TA that determines the success of each transaction
This is why I do not understand people that blame the whales for every single movement of the market, the whales are too big and any movement they make can be easily observed, most of the small movements of the market are instead caused by retail investors trying to beat each other out, what the whales do is to amplify the movements of the market, so if they see a decent pump or dump happening they use their coins to make it bigger and create a bunch of margin calls against the traders using high leverage and create a snowball effect that definitely crashes or makes the market to skyrocket.
we should not blame whales, they are doing their own strategy to earn much profits no matter retail or beginer will be the victim. In this market we should not blame each other and cryptocurrency market work very cruel. Lack of knowledge must be the reason why we easily suffer loss and trapped in whales games.
