What is the current state of matters re tether?
I wondered that too!
After scanning a few results from Googling "tether may 2021 cryto":
-Tether made a settlement "recently" with New York State Attorney General's office
-Settlement included some increased disclosure
-Tether admitted it's not backed by 100% reserves
-Tether stated it's got 74% of its coins backed (at the time of the settlement, I guess)
-Tether stated that most of its reserves are in commercial paper, not cash (which in theory might explain the variance between the Bahamas cash amount and the amount needed to fulfill the 74% claim)
-Actual cash (not the claimed commercial paper) apparently constituted only 2.9% of Tether stablecoins' notional value
Thoughts:
-As commenters on Twitter point out, obviously this means Tether is at best operating as an unregulated bank using fractional reserves, thus vulnerable to bank runs
-If the theory that it's a scam is true, implying that there's not really any any commercial paper, the Ponzi scheme is pretty thin!
-If NY AG verified that the commercial paper is real, the reserves are much better and it might not be a pure scam; but unregulated and vulnerable to runs on the "bank" is still not, well, a very "stable" coin :)
