I'm not sure what losses the class suit is claiming. I think they believe that the Tether manipulation has hurt the price of bitcoin, whereas I think it has currently helped. Though if people start looking deeper into it, instead of just ignoring it as the "same old FUD" - we could go to 1k and then it would really hurt.
What is a good way to distinguish between real bad news and the "same old FUD"? For instance, it took a while to realize that the stories of China banning bitcoin were more complex than a simple yes or no. The Chinese have a complex set of rules designed to limit the use of bitcoin, but they tolerate some uses and mining. It also took time to realize that China banning bitcoin would be largely neutralized by increases in usage in other countries.
On the other hand, the FUD about MtGox ended up being completely real (in that case it was obvious that there was a withdrawal problem from the premium). As did my doubts about all the early bitcoin stocks on the bitcoin stock exchange (some of these were investing in ponzis so...), and all the lending schemes that turned out to be from scammers or ponzis. The ponzis were obvious from the rate of return.
It's my opinion that the doubts about Tether have enough of a scientific basis to warrant serious concern. And as a user of it from 2013 to 2017, the practices of Bitfinex have not always been the most ethical or professional. But they do fall short of being obvious scammers.
Ooh, we need to hire that team that went after GE (and previously went after Madoff) for faking their profits. We need foresnic financial accountants!
https://www.cbsnews.com/news/general-electric-accounting-fraud-bigger-than-enron-alleged-by-madoff-whistleblower/The doubt about ICOs and altcoins is slowly been proven to be true (though it varies on an alt-coin basis with some holding up very well). Though the SEC hasn't gone after the ICOs as much as I'd expected/hoped.

Bearish: Trump could over-react to the move towards impeachment and do something very harmful to the global economy (or he could do something very bullish, though without a majority in Congress it'd be hard to do a tax cut). Like get further intrenched in a trade war or a military war. He's been a bit more off the wall than normal on Twitter.
