Zhao Changpeng CZ said: Hong Kong should not build its own exchange, but directly 'borrow a boat to go to sea.' 'Building a new exchange will cost 1 billion USD and require 300 security experts, so it's better to let Binance operate compliantly in Hong Kong. The money saved can be used to treat everyone to breakfast tea.' Honestly, I agree, and the same goes for the mainland, right?
