Whales: how can someone read the signs and make use of them?

Hi all, i have been trying for a while to follow the “whales’ transactions” and see how the market reacts to them with unfortunately not much luck. I know what a whale is and how their transactions should (at least in theory) influence a coin’s value, however from what I could see the effect is not so clear and I was not so able to use them to “predict” short term value’s fluctuations.

Does anybody on this sub have any useful expierence/insight on the topic? Was any of you ever able to follow the whales to buy/sell coins and make a profit?
