Nothing is completely certain. Take the example of coins delisted by Binance. Initially, Binance didn't delist coins at all, that was from 2018 to 2020. There were indeed few coins, and many projects could just pay a fee to list their coins, as exchanges also need to make money. Later, many coins had significant losses for investors, and exchanges felt it was unattractive, so they started to delist some coins. Over time, Binance became more regulated, and many rules became institutionalized. Coins that are to be delisted will first be placed in an observation area, and if they continue to fail to meet standards, they will be delisted.
The coins that were previously delisted basically just fell; they never rose, often losing half their value. Then, some coins began to rise dramatically after being delisted, experiencing a surge higher than before the drop. This time, the coins that were delisted fell and then surged, only to fall again.
Many coin enthusiasts see a rise and want to buy at the bottom, aiming to catch waves, hoping to find a pattern. However, there really is no规律, and I cannot predict which delisted coins will surge or where they will drop to create an entry point. For such coins, I prefer not to touch them, as they will inevitably fall in the end. The process in between is unpredictable; as long as you can make money, that's what matters. After this drop and surge, will there be another surge for the next delisted coins? I don't know!
