Patience is the key always. Don't panic sell especially when whales or hedge funds are moving the market so fast. Always have a plan before trading to have a minimal losses and maximize the profit.
You and other people that invest in coins can't make as much as someone that is holding the coin while the price is going up. Just have patience.
The best way to shake this behavior is to simply stop paying so much attention to the markets and our portfolios. I am a firm believer in an approach to portfolio monitoring and maintenance that borders on benign neglect. There is so much noise in the markets that the signal typically fades into the background.
