I've always had a question that I'm quite curious about, and I hope someone can clarify it for me: If an exchange is required to comply with regulatory authorities and conduct strict AML checks on users' assets, shouldn't they filter and review the assets when users deposit them into the platform? If the money is problematic, it shouldn't be allowed in from the start, and it should be returned on-chain to the original source. Many platforms operate in a way where they don't ask any questions when users deposit, but when it comes time to withdraw due to regulatory AML factors, they block the withdrawal. This unequal relationship makes users feel like they are being taken advantage of, like being trapped and slaughtered.
