Binance co-founder Changpeng Zhao asked Elon Musk on Friday to stop apparently mocking Binance following a $6.4 billion cryptocurrency theft. Zhao, known as CZ, said Binance's $500 million investment in Musk's Twitter takeover is now worth more than $1 billion in SpaceX shares. Binance co-CEO Yi He said annual revenue can cover the losses without selling those shares. CZ later said CZ had never proposed selling the shares. Binance said the exchange has reserved more than $6.34 billion in company funds to cover the incident.
