Binance has announced that it will delist four cryptocurrency trading pairs on October 4. The pairs to be removed are "ACE/FDUSD, FIL/BNB, OP/BNB, and TRB/FDUSD." While these specific pairs will no longer be available for trading, the related cryptocurrencies will remain listed in the spot market. Binance, known for its strict delisting policies in recent years, also stated that research on cryptocurrency projects will continue, and warning indicators will be added to projects showing negative changes in their token economy.
