BlockBeats News, December 15th, Binance CEO Changpeng Zhao (CZ) said on the "Bonnibel Blockchain" podcast that during the ICO, CZ actively invited Yi He to be a Binance advisor, leading Yi He to participate in the modification and writing of the BNB whitepaper.After the BNB ICO was completed, CZ once again invited Yi He to join the day before BNB was launched, saying, "BNB will be launched tomorrow. If BNB goes up tenfold after the launch, I won't be able to offer you this position, so you either agree today, or we'll have to renegotiate in the future." This conversation ultimately led Yi He to decide to join Binance before the BNB launch.
