Imagine a tricky scenario: you purchase a digital asset account from a certain channel, but unexpectedly, the original owner appears afterward. The other party presents valid and complete identification documents such as an ID card or passport, clearly claiming that the account belongs to them, and requests the platform to reset login passwords, withdrawal permissions, and other critical rights.

What should the platform do at this point? Should it trust the party able to provide genuine identification and complete supporting information, or believe the current account holder's unilateral statement?

This question may seem absurd, but it hits the core of account management issues in crypto exchanges. In the Web3 world, the ownership of accounts often lacks clear judicial precedents for reference. Identity verification mechanisms, multi-factor authentication processes, and risk control reviews all directly influence the final decision.

For exchanges, this is not only a technical issue but also a legal and ethical one—one wrong decision could lead to user assets being stolen. Therefore, most reputable platforms will prioritize trusting the applicant who can provide complete and authentic identity information. This is also why KYC (Know Your Customer) procedures are so important for crypto exchanges.
