An obvious contradiction is the contradiction between the compliance requirements of the exchange and the trading experience of ordinary users. The ideal situation for users, especially ordinary users, is that after doing KYC themselves, they no longer need to worry about compliance, and the institution will conduct transaction review. If there are any problems, they can point out which transaction or operation is problematic, and the user will provide specific explanations. It's difficult, but whoever does it well first, or even commercializes it, is awesome.
