I’m quite interested in hearing the downfall stories of on-chain contract exchanges like DYDX because they’re very insightful. Why didn’t they gradually grow stronger? Why has this field always been about the new replacing the old, with the old dying on the beach? Unlike CEXs, like Binance, which can consistently remain the top in the universe. If there were no trading rewards, or if the rewards are no longer sufficient, would the loyalty of funds still remain? What kind of mechanism could better retain on-chain funds?
