Probably everything is manipulated, or at least Tether has a (direct or indirect) effect on everything in this market.

The difference lies here: BTC maximalists will tell you that Tether is honest because if it goes down, their investment goes down (even if it’s propped up by a scam).

BCH supporters will tell you to let it crash so that honest price discovery can happen again. Even if that means going down for a time.

If it can be destroyed by the truth, it deserves to be destroyed by the truth.
