what about blockfi, with similar interest rates but audited by state of new york regularly?
Tether claimed audits for years, too, and it was bullshit.
https://help.blockfi.com/hc/en-us/articles/360049344531-Why-... ("Unfortunately we're unable to offer the interest account in NY") and https://blockfi.com/licenses/ don't look too promising for this claim, either.
> Unfortunately we're unable to offer the interest account in NY.
> We're hopeful that some of the state rules and regulations surrounding crypto change in the near future so we will be able to offer our interest account in those states. Unfortunately BlockFi's hands are tied until those rules and regulations change as we take our Compliance extremely seriously.
