AMLBot: Tether's frozen assets are 30 times that of Circle, and Tron accounts for over 53% of USDT's frozen assets.

A report by blockchain forensics firm AMLBot reveals that between 2023 and 2025, Tether and Circle respectively frozen $3.3 billion and $109 million in crypto assets through their freezing mechanisms, a difference of approximately 30 times. During this period, Tether blacklisted 7,268 addresses, cooperating with US law enforcement on over 2,800 of them, and recovered some fraudulent and criminal funds through a "freeze + destroy + reissue" mechanism; over 53% of the frozen USDT was located on the Tron network. In contrast, Circle adopted a more conservative strategy, freezing only 372 addresses and $109 million upon court or regulatory requests, without reissuing or destroying tokens.
