My upvote on your post isn't worth anything, but a healthy critique of any system is necessary and welcomed for the continued longevity of said system, so there. I'd hate to be labeled a FUDder on my first day using Steemit but you can search tether on medium or look at @bitfixed on twitter for a collection of articles and information on a couple of alarming problems with crypto that might have led to the price action that's been seen. In addition to huge levels of FOMO, in short, 7 of the top 10 exchanges use tether, the majority do not have true fiat pairing at all, USDT cannot even be used by US customers now because the creators of tether fear imminent US regulatory scrutiny (and have possibly already been targeted as canaries at one exchange have gone missing), and are speculated to be used in the pumping of various alt-coins and Bitcoin itself.
Not looking to hate on crypto itself or the technology, but I think that if the price were to crash then posts such as yours do a service to the community by reminding people what the original mission should be, and it was definitely not supposed to be any sort of scheme to get rich quick. Lasting change won't come from money changing hands rapidly enriching a few early adopters, it comes from long-term systemic changes in the way people view technologies, the impact of their uses and how they can participate in systems that are more beneficial to the whole instead of the few.
