...Binance and many other (reputable exchanges ) delist tokens/coins due to incapability and devaluation.
I used to think so too, but after dumping Luna and delisting this coin on Binance and other exchanges, I see that the situation is generally incomprehensible. The coin, which has lost 99.9% in price, is again traded on Binance after delisting, contrary to the rules of the cryptocurrency exchange. This indicates that the rules are applied selectively.
If I remember correctly the binance exchange has a big position on Luna, if I am indeed correct then at least to me it is obvious that what they are pursuing is for the coin to recover and then begin to exit their position slowly so they can regain some of the money they lost, and then after some time has passed they may once again delist the coin and let someone else become the bag holder while they get some money out of the disaster formerly known as Terra Luna.
