Sam Bankman-Fried, CZ Battle It Out on Twitter Over Binance's Exit from FTX

CORRECTION (Dec. 9, 14:48 UTC): A previous version of this story incorrectly tied the dispute to Binance's aborted acquisition of FTX last month, instead of Binance's exit from its investment in FTX in 2021.

Former FTX CEO Sam Bankman-Fried is embroiled in a war of words with Binance CEO Changpeng "CZ" Zhao on social media, with the pair squabbling over FTX's buyout of Binance's investment in it in 2021.

"You won, there's no need to lie" Bankman-Fried remarked on Twitter after CZ labeled him as a "fraudster" in an earlier tweet.

The dispute stems from Binance exiting its investment in FTX in 2021, with Bankman-Fried claiming that CZ threatened to walk away from the deal if FTX didn't pay an extra $75 million.

For his part, CZ claimed that Bankman-Fried became "unhinged" and that he launched a series of offensive tirades after Binance decided to pull out as an investor.

The former FTX CEO replied: "You threatened to walk at the last minute if we didn't kick in an extra $75m. We did it anyway because this just made us feel more confident... But again, none of this is necessary. You won. Why are you lying about this now?"

FTX eventually filed for bankruptcy last month with billions of dollars of client funds being lost, and Bankman-Fried resigned after what is considered a Lehman Brothers moment for the crypto industry.
