So why doesn't the NYAG charge them with the most obvious scam in history according to HN? If it's so clear from outside that Tether is not backed by actual dollars, how come the NYAG which has subpoena power and so one doesn't latch on such an easy and infamous case?
I'll give you a few minutes to read [1] and [2] before I reply earnestly. I know it takes more than 10 minutes to read them because, and this is true, I have read them. The answer to your questions is there. They did.
Why did they stop at a fine? I don't know. Maybe there were jurisdictional issues, maybe the Feds were/are looking at it. Heck maybe they thought it would be better if the thing fell in on itself so they weren't viewed as the entity that took down crypto. I dont work at DoJ so I can't tell you. Doesn't change anything though.
On the other hand I've given you plenty of night-time reading where you can find the answers to basically every question you've asked me.
