Today, Musk refollowed CZ after replying to CZ's tweet.

Yesterday, CZ posted that he was glad to contribute to the acquisition of Twitter (X), while also sharing the news that Binance invested 500 million dollars in Musk's acquisition of Twitter. Musk responded to this.

What is Twitter? Someone just asked me! Let me explain.

Twitter is X, also known as Twitter; there's no need for everyone to research what project it is.
