Tether, which is the most used so-called "stablecoin" (As its value is pegged to the USD) is extremely seedy at best and has had brushes with the law already [0] or is outright a Ponzi scheme [1] and plenty of people arguing for/against crypto know and have said so already.

Personally, even though I'm a proponent of cryptocurrency in general, I wish it'd disappear in spite of any short and middle-term calamitous consequences on perceived value if that means one less "dumbed-down club" (Using dang's words) when it comes to discussing crypto.
