This is one of the reasons why centralized exchanges are not a good idea, because governments will control these entities. Today it is investigations against manipulators or speculative investors and tomorrow it is a witch hunt against all Crypto currency owners. The KYC/AML regulations identifies all Crypto currency users that use these exchanges, so a raid on these people can be easily arranged with that data.
Make sure you do not store all your Crypto currency info and paper wallets in the location you gave up to these exchanges.
