You do not have to protect yourself against Whale rinse and repeat trades, when you ignore the short-term volatility. Any long-term trader will simply ignore this and just sit back and wait for the price to reach a new ATH and then to take some profits.
The day trader will actually benefit from this volatility by buying low and selling high. So depending on how you approach trading, you should actually benefit more from this kind of rinse and repeat trades by these Whales.
