It is even worse than that... I think they published only a sort of pie diagram and provided the % for each of that asset classes they hold to back their Tether, but nobody knows how much value the assets they hold to back Tether really have!
They could provide a pie diagram and have less than a million available to back billions of Tether. What a ridiculous report!

There has been no independent audit. We know what they have revealed so far. And there is no guarantee that they are saying the truth. I still don't know why people prefer USDT over other more reliable stablecoins.
