According to ChainCatcher, Whale Alert monitored that at 17:39:23 Beijing time, an address containing 5,300,000 USDT was just frozen.
It is reported that the power to freeze USDT is in the hands of Tether. As the issuer of USDT, Tether has the authority to freeze USDT addresses. It can choose to freeze the entire USDT address or only freeze the USDT balance in the address without affecting other crypto assets in the address itself. Usually Tether will decide whether to freeze a USDT address based on legal compliance, anti-money laundering and other considerations.
