Last Updated: Nathaniel Popper, a New York Times reporter, stated in a tweet that the quotes to appear were delivered on December 6 not last week, according to the familiar source of the question.

Major exchange of Bitfinex cryptocurrency and token issuer Tether have received assignments from US regulators as questions continue to arise regarding the "true" value of the latter.

In reactions to the news, commentators of the cryptocurrency industry had mixed opinions

Meanwhile, the Bitcoin prices plummeted Tuesday, likely in part because of the news. Charlie Shrem considered that the sale of Bitcoin was "really stupid" because Tether's securities presented the risk and the cryptocurrency represented an "exit" of the financial losses.
