Tencent's chief exploration official website said that I am basically not likely to invest in such platform-level services as blockchain, AI (artificial intelligence), VR (virtual reality) and so on. I have invested in companies that solve specific problems. It's just a means to solve the problem. My work focuses on responding to global challenges. In this context, blockchain is actually a tool. The problem is how to make this tool help various global challenges. If the blockchain cannot make a significant impact on these areas, the CXO team will not be involved in this area.
