A while ago, I was chatting with some friends who are involved in traditional businesses, and they raised an old question: "What exactly is Web3 useful for? Isn't it just hype?" I didn't argue directly at the time; instead, I showed them a page from a DeFi platform. I told them to put aside those unreliable projects for now and carefully consider what the fundamental competitive advantage of Web3 is—simply put, it's "capital efficiency." Think about it: money in traditional banks earns a tiny interest rate per year, which, to be blunt, is just symbolic tipping. But within the Web3 ecosystem, the potential returns generated by the same amount of capital are on a completely different level. This is the core difference.
