I'm not sure what's worse: the fact that an important chunk of Tether can be with blocked with just the slightest due process, or the fact that that the same lack of due process can keep addresses unblocked.
It's also hilarious how different parts of the executive branch seem to be at odds with each other over what to do. Treasury says blacklist now, ask questions later, and DoJ says (or might at least be thinking) wait, wait - don't blacklist, we're following perps on the blockchain.
Those who believe that the long arm of the law is bearing down on Tether might want to consider the possibility that Tether will remain operational much longer than seems reasonable. As revealed in this article, it's become a very useful tool for conducting criminal investigations.
