This article goes to great alarmist lengths, past the point of being deceiving. Just the very first line:

> One of the world’s most widely traded virtual currencies faces renewed doubts about its stability [...]

Tether is nothing in terms of crypto currency penetration. It does not even have a percent of daily trading. Then a few paragraphs down:

> [...] within an hour of the attorney general’s statement and Tether slid 1.4 percent.

1.4 per cent. Even big cap stocks fluctuate that much some days.

> At the time of the correspondence, Bitcoin was trading at around $6,500. It dropped 4.7 percent to $5,236.03 at 12:10 p.m. in Hong Kong on Friday.

So they mention a price from 8 months ago, and then mention yesterday's price, implying that it fell that much because of this event.

Garbage journalism.
