Depending on how the hacking takes place, I can see them convert the USDT to other tokens and withdraw the deposits from there. I guess that's one plus point for Tether, although I don't think anyone is comfortable knowing Tether can freeze their tokens anytime regardless of what they do. Especially when the rate of abuse and control is high.
How can it be a plus point for Tether? I mean, besides only an increment in their trading volume, I don't see another plus point. And if they would be seeking plus points, they won't acquire this feature in the first place I guess.
But this feature is also a plus point for them to make a good image among authorities and governments for their longevity. Yeah, no one really be comfortable to keep their funds in USDT form because for a single users if he keeps $1000 to $10,000 how can he reach out to the Tether team so they could seize the funds when his wallet gets hacked? There is not enough time for them in the first place so I think this feature of them is not so useful as hackers are now aware of this reality.
PS: There is another side to it that no one might be uncomfortable with them being in control of their USDTS while everything is becoming so centralized so why not their funds and for them they at least have the option to seize funds, which means there is some chance to recover lost funds as, Tether almost recovered $1.8 Billion funds if I am not wrong.
