According to Foresight News, CZ responded to "community inquiries about the BUSD situation" by saying, "BUSD is an excellent USD stablecoin, but it was killed in the HT Operation Chokepoint 2.0. On the positive side, many new stablecoins are now being launched on BSC."
Foresight News notes that Operation Chokepoint 2.0 is a liquidation operation led by the Biden administration targeting the cryptocurrency industry, making US financial institutions uncooperative or unwilling to provide services related to crypto projects.
