Snapshot Limitations
Snapshot limitations refer to the inherent weaknesses of auditing an exchange at a single point in time. Because digital asset markets move rapidly, a Proof of Reserves snapshot can be rendered obsolete minutes after it is taken.
Exchanges could theoretically borrow assets temporarily to inflate their balance sheet just for the audit and then return them afterward. Furthermore, a snapshot does not provide information about the quality of the assets held or the exchange's ongoing operational cash flow.
To be truly effective, auditing must move toward continuous, real-time monitoring rather than periodic snapshots to provide a genuine picture of financial health.
