The washout is actually just a trick by those small-cap market makers: lacking confidence, they can only rely on silence, intimidation, and gradual declines to confuse retail investors and keep the market quiet. When the opportunity arises, they scoop up chips at low prices; if that fails, they abandon the market directly. To be honest, such market makers are really low-level.
So, what about the truly impressive market makers? They don't even need to crash the market. The most clever washout is actually a price increase. If it doubles and you don't sell, fine; what if it increases five times? Ten times, twenty times, fifty times, or even a hundred times? There will always be a moment when you can't withstand the pressure and sell. Once you've sold off, the market continues to rise, and 80% of people who see a few times their investment will want to go all in, but their cost basis will be too high, making it hard to exit. When the market maker thinks it's about time, they harvest once again, maximizing profits and making a fortune.
