This is the reality that is why the small investors are at a disadvantage at times when the whales move. What we, small investors can do about it is to at least have some clue of the whales activity because in this way, we can act upon their move and be able to move in sync with them. According to the article, it is not illegal for the whales to collude to manipulate the market because bitcoin is not a security that's why they can freely do what they want but then if ever they do discuss and work together like sell a bulk of coins then there are many willing buyers ready to grab some at the bottom that's why bitcoin may not collapse.
