More than 20 years ago, Taobao was like this. All sorts of amazing things and services, including Bitcoin, could be bought and sold on Taobao, hence the saying that Taobao is omnipotent. Over the past 20 years, e-commerce has evolved from individual vendors to flagship stores, from secondhand goods to genuine product stores, from being able to sell whatever you want to needing platform approval to sell anything, and from being able to buy whatever you want to sometimes not even being able to find what you want to buy. In short, from decentralized to centralized. Xianyu only retains some of the earliest Taobao C2C model. Those who say Xianyu is the Dark Web clearly haven't seen what the Dark Web is. 😀 Do you prefer e-commerce today or e-commerce 20 years ago?
