I don't see how anyone thinks China will unban crypto trading these years, it goes against everything China plans now with its economy.
China faces a real estate crisis, it needs approximately 2 trillion to prop up prices for its biggest economic sector, do you think it will allow money from private investors to go to a different sector not under their control? They need every penny to go back in housing, why allow it to go somewhere else?
Capital control, is the basic policy of China, they will never allow for a way to transfer wealth without having a tiny bit of control over it, how can anyone assume they will let the population have access to a thing then can send millions ina flash outside their jurisdiction?
Besides, why would China want to let their people invest in assets that would produce billions of wealth for ETH holders in the US?
