> Binance was threatening to dump a huge amount of FTT tokens on the market. FTX has a big+vulnerable position in FTT. FTX asked Binance to sell them the tokens for a fixed price, so as not to crash the FTT token price. Binance declined
This makes absolutely no sense and is not how markets work. If FTX was actually willing to buy unlimited FTT at a given price, Binance could not have "crashed the price" by selling below that price — somebody would simply have bought at the Binance price and sold to FTT at their price.
What seems more likely is that FTX extended that offer only to a small portion of the tokens that Binance wanted to sell (to maintain the fiction of their price).
