Still there have been zero redemption issues in getting USD back from USDT
* Only for holdings of over $30,000
* 90-180 day waiting period
* non-US nationals
It was so bad, that people put out bounties for anyone who could prove that Tether or Bitfinex (whatever, they're the same) had redeemed USDT. I believe one bounty was in the order of $5,000.
The ones I found were unclaimed.
Also, are there entities redeeming USDT into USD? Or does it always involve intermediary crypto? (I am not actually familiar with the extent of cryptoexchanges out there that deal with fiat, so genuinely curious.)
