Good thing there are other stablecoins
Those who don't know how it works, and I believe not everyone knows how centralised USDT is and how their funds can be frozen in their wallets without knowing it, Many people believe that when they have access to their particular wallet, they are in total control over the assets in that wallet. Not everyone knows that even without authorising the movement of coins to another wallet, the funds can be locked up in that same wallet, and their access to withhold them will be withheld.
And talking about centralised exchange, they might probably not know it will happen that quickly for their assets to be frozen in their, or it might be as a result of the owner of such money doesn't even know what to do with it or what token it should be converted to in order not to leave a trace. In cases like this, no one unless those involved can really say the reason why someone who has such funds can't keep their tracks and protect their holdings.
Centralized stablecoins on centralized exchanges. LOL.
