They are under scrutiny, and here are some facts:
- they lied about the reserves and weren't backed at 100%
- they did fraudulent attestations wiring money for the 'snapshot' of accounts for the attestation then moving it back to owners (from Bitfinex exchange if I remember - which is the same people - see a pattern here ?)
- held money in their personal accounts
the above were proven without doubt by the NY AG.
- promised an audit for several years (it's always just a few months away)
- publish attestations that are obviously false. some red flags - in the first one, they claimed to have so much money in commercial paper that would put them in top 10 players - yet, among desks trading those papers, nobody ever heard of them ! In the last 2, if what they published was true, they would already be under water, given the decline of all coins - yet, somehow they are all okay.
- each time an exchange / scam goes down - they publish those papers saying they have 0 exposure to them (recently FTX, Genesis) - this despite findings that Alameda (FTX affiliated hedge found) was on the recepient of >30% of all Tethers
- last I checked, their CEO wasn't seen publicly for several years. Most of their financial 'communication' is done by their AG and 'the IT guy'
There are many more. In case of doubt, watch this interview and judge yourself if this feels like guys legitimately managing 70B real dollars:

It's all scam - it's so obvious that it's amazing. It will collapse - we just don't know when.
