As a noob who owns some bitcoin and ethereum (both stored on an exchange), how does tether being a scam (which I do believe in) affect me? I don't hold any tether myself.
2 - If you believe the worst allegations, then Tether is artificially propping up the value of Bitcoin. In the event of a run on Tether, Tether may be forced to sell thousands of Bitcoins abruptly onto the market to get cash.
3 - The fallout of a true worst case scenario for Tether could lead to crypto being reclassified in order to fall under all the relevant financial regulations that banks and the traditional finance sector are subject to.
