1. Is not an audit to be used for assurance purposes. The disclaimer at the top states that it "should not be used or relied on by any other party."
2. Is rather old now.
3. Was conducted by a firm that no longer conducts business with Tether, probably because Tether would not comply with information requests needed to conduct an actual audit, which is not as difficult as Tether makes it sound here: https://www.coindesk.com/tether-confirms-relationship-audito...
Or in other words, it isn't proof of anything, and the fact that Tether has not been able to produce an actual audit for assurance purposes in all this time, speaks volumes.
