It's understandable that many say "whales can't be played."

Because this thing is indeed controlled by whales for both rises and falls.
But the logic of whale coins has never been about "predict when whales will start or dump."
Instead, it's about finding the characteristic that fits: this characteristic is "a trend has already formed, and if a whale intentionally goes against this 'momentum,' the profit is less than the cost."
So, you can't guess the absolute top or bottom, but rather identify the current wave, find signals that match this wave's characteristics.
The last line of defense is to always set a stop-loss, profit based on losses, and there's no need to pursue a high win rate.
Among all the whale coin strategies I am currently testing, the best performance still comes from short-selling strategies based on breaking K-line trends, avoiding almost all false retracement traps and fake dips.
The OI strategy triggers very frequently, but the cost of manipulation is too low (this isn't about chip costs).
It has a high win rate, but the cumulative PNL is relatively poor.
