ICOs are a more immediate threat to un-savvy investors. Tether may also die or 'exit' on its own.

Maybe they don't want to say anything while the investigation is ongoing.

Footnote 11 on page 5: "I am particularly concerned about market participants who extend to customers credit in U.S. dollars – a relatively stable asset – to enable the purchase of cryptocurrencies, which, in recent experience, have proven to be a more volatile asset."

There have not been any new Tether grants (pumps) since Jan 23 and the price is collapsing accordingly.

Tether is none of the US's business. Headquartered in Hong Kong.

I don't understand why folks are making such a big deal about Tether. If it is indeed a scam, wouldn't that imply a $2-$3 billion scam at most? What am I missing? As of this writing, the entire crypto market cap is at a recent low of $300 billion. Tether would be around 1% of the total market.

The value of the crypto which is actually in flight in day-to-day trading is probably orders of magnitude less than that, though.
