Looking up to his recent tweets, he kinda shuts up about crypto for a while though I am sure that once the "Twitter change" topic has died off, he would continue to do so. If he is going to make his own "coin", it would surely do terrible as you know that people really just read the headlines these days and they do not care a single bit on why he just fired a lot of people from Twitter. It is going to be filled with FUD for sure in the first day. He would indeed stay away, well at least for now. Maybe in the next decade, he will depending on how it turns out on his "post-Twitter" topic.
