The New York Times: Zhao Changpeng once criticized SBF in a group chat for attacking USDT through a $250,000 transaction
ChainCatcher message, materials obtained by The New York Times show that on November 10, Zhao Changpeng criticized SBF for deliberately undermining Tether's stability through his hedge fund Alameda in a group chat that included several leading figures in the crypto industry. In response to Zhao Changpeng's accusation, SBF appeared bewildered: "Huh? What did I do to the stablecoin? Do you mean you think a $250,000 USDT trade would unpeg it?"
Zhao Changpeng continued to respond that he did not believe such a trade could successfully destroy Tether, but it would still cause problems. "My sincere advice is: stop everything you are doing. Put on your suit and go back to Washington to start answering questions."
SBF then replied: "Such a trade would not have any material impact on Tether. To my knowledge, neither I nor Alameda have attempted to deliberately unpeg Tether or any other stablecoin." "I have made many mistakes over the past year, but this is not one of them." (source link)
