According to online reports, Binance founder CZ said on the suggestion of using angel investment to support early innovative projects,"It's trying. I am generally good at judging people, but it takes time. To understand an entrepreneur, we need to observe how he makes decisions and executes under various pressures, the temptation of money, and the interests of users. There is also whether you are hardworking, flexible, understand the market, world view, leadership, etc. It's not like chatting for a while to understand everything. At least I don't have the ability. I voted for Trust Wallet back then, although I only met him once. But I've been observing them for some time before. In fact, this is what YZi Labs is doing. But investment requires a lot of time investment. It's not so magical."
