If the whales are secretly buying up Bitcoin than I will buy Bitcoin at the current market rate. Even if it goes to 2500$. Gives me sum hope in the crypto space. Only if I find out they are buying through forums etc.
You should be the one deciding for yourself if you want to buy Bitcoin and not following whales, you should invest what you can afford to lose, and your decision should be on your own analysis and not just because you are following a certain group of people, that will not work, whales also losses but they have the means to always come back.
