It's also a testing opportunity. Those who have crypto that came directly from eXch exchange can test other services that claim to be no KYC and not requiring AML and SoF checks. It's a great way to check if they will allow you to execute swaps or freeze your crypto and demand that you provide them with all sorts of information and documents. And in case you refuse, will you get a refund or will the money remain in their hands until you comply.
