ChainCatcher news, Binance co-founder Changpeng Zhao posted on X: "A live demonstration is worth a thousand words.Many people tried to pitch their projects to me at the conference, often taking selfies with me as well. This doesn't work. I'm not smart enough to understand a project in a few seconds.Business cards are more useful to me. I can easily hand them to my team, which is much easier than asking me for contact information."
