Blockchain Forensics Agency AMLBot reports that between 2023 and 2025, Tether and Circle, through freezing mechanisms, have collectively blocked $3.3 billion and $109 million in crypto assets, respectively, with a scale difference of about 30 times. During this period, Tether blacklisted 7,268 addresses, over 2,800 of which were handled in collaboration with US law enforcement agencies, and recovered some scam and criminal funds through the "freeze + burn + reissue" mechanism; over 53% of frozen USDT are on the Tron network. In contrast, Circle adopts a more conservative strategy, freezing only 372 addresses and $109 million upon court or regulatory orders, without reissuing or burning tokens.
