Very hard to do. The first advantage of Whales in crypto market is having 0-fee trading. With trading fees >0 it becames very difficult to take advantages on market volatility. And following whales is what whales want. They use iceberg orders, insider trading and many tools that are invisible to other market participants. So "think like whales" frequently becames "oh, whales are crashing market, time to sell". So be careful!
