They indeed freeze assets, but it shouldn't be worry for normal users, even USDC freezes assets, so this is something that is similar to all centralized stable coins. Tether publishes transparency report [1] daily, so I'm unsure why they have suspicious status in category of stable coins. I'm gonna seek clarification from forum users.

https://tether.to/en/transparency/#usdtGreat I would appreciate and would humbly learn too. If they freeze assets, how do you mean it shouldn’t be a worry for normal users? How are you defining normal users? I’m a normal user and for the times I’ve used USDT, I have never had any challenges, but then I worry for the fact that someone somewhere has the ability to freeze my USDT. I mean, isn’t this exactly what the traditional banking system does? Considering that it’s the same case with USDC, I may prefer to stick to USDT. However, maybe Bitcoin is really the best after all.
As long as your funds aren't coming from shady sources, I would call you a normal user

Yea, it's similar to traditional banking but there are some pros here like you can exchange easily to or from usdt/usdc without kyc (on instant exchanges/dexes — if cexes require kyc), and also no worry even if you convert huge amounts unlike in banks where if it were $10k you'd be asked whereabouts it came, why are you withdrawing, etc
Apparently people who use Bitcoin are not necessarily into something shady. Right? But then, we rather use Bitcoin instead of the bank because we have complete control over our money and no one can have any power over it. People expect nothing less from USDT. Yes, we may not be affected since we aren’t doing anything shady. However, the feeling of knowing that nobody can do anything to your money is priceless. So, we may not encounter any issue, but one needs to know that they completely have control and no one can do otherwise.
