There is nothing strange about CZ not using DEX to add LP pools. People have path dependencies. After working in CEX business for ten years, they only think about how to do a better job in centralized business. The decentralized DEX business is not in his vision at all. There is no need to pay attention to it before encountering life-death competition (so now it is time for life-death competition between CEX and DEX). ​ Similarly, after three years of doing things related to chain games, it is difficult to leave even if the chain game track is in a downturn. The cost of sunk is too high, so expand the scope and keep building!
