What are the most common mistakes in payment investigations?¶

The recurring mistake is collapsing account, instrument, endpoint, transaction and person into one conclusion before their relationships are proved.

Interpretation errors compound quickly¶

Examples include equating holder with user, screenshot with provider history, authentication with informed consent, receipt with benefit and blockchain address with identity. Other errors include confusing timestamps and statuses, recording the wrong network or token, ignoring internal transfers, fees and conversions, or stopping at the first recipient.

Preservation and requests can create further gaps¶

Opening applications, changing passwords or revoking endpoints without a log can alter evidence. Vague provider requests omit stable identifiers. Failure to test shared access, compromise, remote control or deception makes attribution brittle.

The remedy is to preserve identifiers early, reconcile provider and endpoint records, trace proportionately and keep facts and inferences separate.
